A localized defect in the visual field bordered by an area of normal vision. This occurs with a variety of EYE DISEASES (e.g., RETINAL DISEASES and GLAUCOMA); OPTIC NERVE DISEASES, and other conditions.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

The effect of face inversion on activity in human neural systems for face and object perception. (1/5692)

The differential effect of stimulus inversion on face and object recognition suggests that inverted faces are processed by mechanisms for the perception of other objects rather than by face perception mechanisms. We investigated the face inversion using functional magnetic resonance imaging (fMRI). The principal effect of face inversion on was an increased response in ventral extrastriate regions that respond preferentially to another class of objects (houses). In contrast, house inversion did not produce a similar change in face-selective regions. Moreover, stimulus inversion had equivalent, minimal effects for faces in in face-selective regions and for houses in house-selective regions. The results suggest that the failure of face perception systems with inverted faces leads to the recruitment of processing resources in object perception systems, but this failure is not reflected by altered activity in face perception systems.  (+info)

Impairment in preattentive visual processing in patients with Parkinson's disease. (2/5692)

We explored the possibility of whether preattentive visual processing is impaired in Parkinson's disease. With this aim, visual discrimination thresholds for orientation texture stimuli were determined in two separate measurement sessions in 16 patients with idiopathic Parkinson's disease. The results were compared with those of 16 control subjects age-matched and 16 young healthy volunteers. Discrimination thresholds were measured in a four-alternative spatial forced-choice paradigm, in which subjects judged the location of a target embedded in a background of distractors. Four different stimulus configurations were employed: (i) a group of vertical targets among horizontal distractors ('vertical line targets'); (ii) targets with varying levels of orientation difference on a background of spatially filtered vertically oriented noise ('Gaussian filtered noise'); (iii) one 'L' among 43 '+' signs ('texton'), all of which assess preattentive visual processing; and (iv) control condition, of one 'L' among 43 'T' distractors ('non-texton' search target), which reflects attentive visual processing. In two of the preattentive tasks (filtered noise and texton), patients with Parkinson's disease required significantly greater orientation differences and longer stimulus durations, respectively. In contrast, their performance in the vertical line target and non-texton search target was comparable to that of the matched control subjects. These differences were more pronounced in the first compared with the second session. Duration of illness and age within the patient group correlated significantly with test performance. In all conditions tested, the young control subjects performed significantly better than the more elderly control group, further indicating an effect of age on this form of visual processing. The results suggest that, in addition to the well documented impairment in retinal processing, idiopathic Parkinson's disease is associated with a deficit in preattentive cortical visual processing.  (+info)

Accurate memory for colour but not pattern contrast in chicks. (3/5692)

The visual displays of animals and plants often look dramatic and colourful to us, but what information do they convey to their intended, non-human, audience [1] [2]? One possibility is that stimulus values are judged accurately - so, for example, a female might choose a suitor if he displays a specific colour [3]. Alternatively, as for human advertising, displays may attract attention without giving information, perhaps by exploiting innate preferences for bright colours or symmetry [2] [4] [5]. To address this issue experimentally, we investigated chicks' memories of visual patterns. Food was placed in patterned paper containers which, like seed pods or insect prey, must be manipulated to extract food and their patterns learnt. To establish what was learnt, birds were tested on familiar stimuli and on alternative stimuli of differing colour or contrast. For colour, birds selected the trained stimulus; for contrast, they preferred high contrast patterns over the familiar. These differing responses to colour and contrast show how separate components of display patterns could serve different roles, with colour being judged accurately whereas pattern contrast attracts attention.  (+info)

Integration of proprioceptive and visual position-information: An experimentally supported model. (4/5692)

To localize one's hand, i.e., to find out its position with respect to the body, humans may use proprioceptive information or visual information or both. It is still not known how the CNS combines simultaneous proprioceptive and visual information. In this study, we investigate in what position in a horizontal plane a hand is localized on the basis of simultaneous proprioceptive and visual information and compare this to the positions in which it is localized on the basis of proprioception only and vision only. Seated at a table, subjects matched target positions on the table top with their unseen left hand under the table. The experiment consisted of three series. In each of these series, the target positions were presented in three conditions: by vision only, by proprioception only, or by both vision and proprioception. In one of the three series, the visual information was veridical. In the other two, it was modified by prisms that displaced the visual field to the left and to the right, respectively. The results show that the mean of the positions indicated in the condition with both vision and proprioception generally lies off the straight line through the means of the other two conditions. In most cases the mean lies on the side predicted by a model describing the integration of multisensory information. According to this model, the visual information and the proprioceptive information are weighted with direction-dependent weights, the weights being related to the direction-dependent precision of the information in such a way that the available information is used very efficiently. Because the proposed model also can explain the unexpectedly small sizes of the variable errors in the localization of a seen hand that were reported earlier, there is strong evidence to support this model. The results imply that the CNS has knowledge about the direction-dependent precision of the proprioceptive and visual information.  (+info)

Orientation-tuned spatial filters for texture-defined form. (5/5692)

Detection threshold for an orientation-texture-defined (OTD) test grating was elevated after adapting to an OTD grating of high orientation contrast. Threshold elevation was greatest for a test grating parallel to the adapting grating, and fell to zero for a test grating perpendicular to the adapting grating. We conclude that the human visual system contains an orientation-tuned neural mechanism sensitive to OTD form, and propose a model for this mechanism. We further propose that orientation discrimination for OTD bars and gratings is determined by the relative activity of these filters for OTD form.  (+info)

Monocular occlusion cues alter the influence of terminator motion in the barber pole phenomenon. (6/5692)

The influence of monocular occlusion cues on the perceived direction of motion of barber pole patterns is examined. Unlike previous studies that have emphasized the importance of binocular disparity, we find that monocular cues strongly influence the perceived motion direction and can even override binocular depth cues. The difference in motion bias for occluders with and without disparity cues is relatively small. Additionally, although 'T-junctions' aligned with occluders are particularly important, they are not strictly necessary for creating a change in motion perception. Finally, the amount of motion bias differs for several stimulus configurations, suggesting that the extrinsic/intrinsic classification of terminators is not all-or-none.  (+info)

Local velocity representation: evidence from motion adaptation. (7/5692)

Adaptation to a moving visual pattern induces shifts in the perceived motion of subsequently viewed moving patterns. Explanations of such effects are typically based on adaptation-induced sensitivity changes in spatio-temporal frequency tuned mechanisms (STFMs). An alternative hypothesis is that adaptation occurs in mechanisms that independently encode direction and speed (DSMs). Yet a third possibility is that adaptation occurs in mechanisms that encode 2D pattern velocity (VMs). We performed a series of psychophysical experiments to examine predictions made by each of the three hypotheses. The results indicate that: (1) adaptation-induced shifts are relatively independent of spatial pattern of both adapting and test stimuli; (2) the shift in perceived direction of motion of a plaid stimulus after adaptation to a grating indicates a shift in the motion of the plaid pattern, and not a shift in the motion of the plaid components; and (3) the 2D pattern of shift in perceived velocity radiates away from the adaptation velocity, and is inseparable in speed and direction of motion. Taken together, these results are most consistent with the VM adaptation hypothesis.  (+info)

Chromatic masking in the (delta L/L, delta M/M) plane of cone-contrast space reveals only two detection mechanisms. (8/5692)

The post-receptoral mechanisms that mediate detection of stimuli in the (delta L/L, delta M/M) plane of color space were characterized using noise masking. Chromatic masking noises of different chromaticities and spatial configurations were used, and threshold contours for the detection of Gaussian and Gabor tests were measured. The results do not show masking that is narrowly-selective for the chromaticity of the noise. On the contrary, our findings suggest that detection of these tests is mediated only by an opponent chromatic mechanism (a red-green mechanism) and a non-opponent luminance mechanism. These results are not consistent with the hypothesis of multiple chromatic mechanisms mediating detection in this color plane [1].  (+info)

Potentially identical objects (e.g., files) are located across multiple computers based on stochastic partitioning of workload. For each of a plurality of objects stored on a plurality of computers in a network, a portion of object information corresponding to the object is selected. The object information can be generated in a variety of manners (e.g., based on hashing the object, based on characteristics of the object, and so forth). Any of a variety of portions of the object information can be used (e.g., the least significant bits of the object information). A stochastic partitioning process is then used to identify which of the plurality of computers to communicate the object information to for identification of potentially identical objects on the plurality of computers.
In an attempt to understand how low-level visual information contributes to object categorisation, previous studies have examined the effects of spatially filtering images on object recognition at different levels of abstraction. Here, the quantitative thresholds for object categorisation at the basic and subordinate levels are determined by using a combination of the method of adjustment and a match-to-sample method. Participants were asked to adjust the cut-off of either a low-pass or high-pass filter applied to a target image until they reached the threshold at which they could match the target image to one of six simultaneously presented category names. This allowed more quantitative analysis of the spatial frequencies necessary for recognition than previous studies. Results indicate that a more central range of low spatial frequencies is necessary for subordinate categorisation than basic, though the difference is small, at about 0.25 octaves. Conversely, there was no effect of categorisation level
An object tracking method uses a system having an object identifying device and at least one video tracking device, wherein the object identifying device monitors an area to identify an object entering the area and the video tracking device wired/wirelessly connected to the object identifying device monitors the area monitored by the object identifying device. The method includes: extracting, at the object identifying device, object identification information of the object; providing, at the object identifying device, the object identification information to the video tracking device; tracking, at the video tracking device, the object to extract physical information of the object; mapping, at the video tracking device, the physical information to the object identification information to generate object information of the object; and storing, at the video tracking device, the object information in a memory of the video tracking device.

Objects that are semantically related to the visual scene context are typically better recognized than unrelated objects. While context effects on object recognition are well studied, the question which particular visual information of an objects surroundings modulates its semantic processing is still unresolved. Typically, one would expect contextual influences to arise from high-level, semantic components of a scene but what if even low-level features could modulate object processing? Here, we generated seemingly meaningless textures of real-world scenes, which preserved similar summary statistics but discarded spatial layout information. In Experiment 1, participants categorized such textures better than colour controls that lacked higher-order scene statistics while original scenes resulted in the highest performance. In Experiment 2, participants recognized briefly presented consistent objects on scenes significantly better than inconsistent objects, whereas on textures, consistent objects were

The visual system must extract from the light that falls on the retina meaningful information about what is where in our environment. At an early stage it analyzes the incoming sensory data along many dimensions of pattern vision, e.g. spatial frequency, orientation, velocity, eye-of-origin. Visual Pattern Analyzers provides a definitive account of current knowledge about this stage of visual processing.
Fig. 2. Neural-like models via performance optimization. (A) We (1) used high-throughput computational methods to optimize the parameters of a hierarchical CNN with linear-nonlinear (LN) layers for performance on a challenging invariant object recognition task. Using new test images distinct from those used to optimize the model, we then (2) compared output of each of the models layers to IT neural responses and the output of intermediate layers to V4 neural responses.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We study the problem of generating plausible interpretations of a scene from a collection of line segments automatically extracted from a single indoor image. We show that we can recognize the three dimensional structure of the interior of a building, even in the presence of occluding objects. Several physically valid structure hypotheses are proposed by geometric reasoning and verified to find the best fitting model to line segments, which is then converted to a full 3D model. Our experiments demonstrate that our structure recovery from line segments is comparable with methods using full image appearance. Our approach shows how a set of rules describing geometric constraints between groups of segments can be used to prune scene interpretation hypotheses and to generate the most plausible interpretation.

Functioning in the Earth gravity field imposes on living organisms a necessity to read directions. The characteristic feature of their bodies, regardless unicellular or multicellular, is axial symmetry. The development of body plan orchestrated by spatiotemporal changes in gene expression patterns is based on formation of the vertical and radial axes. Especially for immobile plants, anchored to the substrate, vertical axis is primary and most important. But also in animals the primary is the axis, which defines the anterior and posterior pole of the embryo. There are many little known chiral processes and structures that are left- or right oriented with respect to this axis. Recent developments indicate the role of intrinsic cell chirality that determines the direction of developmental chiral processes in living organisms. The still enigmatic events in cambia of trees and handedness of phyllotaxis as well as plant living crystals are in focus of the chapter.
Abstract: Mirror symmetry, in a crude formulation, is usually presented as a correspondence between the Gromov--Witten theory of a Calabi--Yau variety $X$, and some invariants extracted from the degeneration of Hodge structures of a mirror family of Calabi--Yau varieties $\mathcal{X}^{\vee}\to\mathbf{D}$. After physicists Bershadsky--Cecotti--Ooguri--Vafa (henceforth BCOV), this is organised according to the genus of the curves in $X$ we wish to enumerate, and gives rise to an infinite recurrence of differential equations. The first equation in the recurrence amounts to the classical genus zero mirror symmetry considered by Candelas--de la Ossa--Green--Parkes, and is nothing but an expression of the Yukawa coupling of the mirror family in terms of the genus 0 Gromov--Witten invariants of $X$. The Yukawa coupling is indeed an invariant of the degeneration of Hodge structures (in the middle degree) of $\mathcal{X}^{\vee}\to\mathbf{D}$. Many instances of the genus 0 conjecture are nowadays known, ...

Combines the Real and Imaginary data sets to one array for exporting to the Simepr.exe program. You must use this feature to Optimize or Tune an FT spectrum. This feature has no meaning for a CW spectrum. Only a symmetric spectrum which is centered in the data array will produce a Fourier transform which is purely either Real or Imaginary depending on the harmonic with the exception of noise. A first derivative CW spectrum will produce a purely Imaginary display after an FFT+1. To simulate the FT of non-symmetric and/or non-centered spectra, this feature has been added. Because the spectral information is compressed into the low frequency region of an FT by the exponential linewidth function, the high frequency region may be discarded. This now empty space of the Imaginary array is used to hold the low frequency information of the Real array. You will be prompted for n, the frequency value (data point) for combination. This number should be above the region of significant low frequency spectral ...

A method of sharing a group of one or more objects between a plurality of users, in which one or more of said plurality of users is able to change parameter data of at least one said object. The method comprises storing at least one version of each said object; when an object is changed, creating a new version of the object, the new version of the object comprising additional data relating to the creation of the new version; storing the new version of the object together with any version of that object before the change; providing all versions of the object to each of said plurality of users; and using the additional data provided for each version of the object to determine how to display the object. The group may be a calendar and each object may be an event in the calendar. In that case, the object parameter data may comprise a start time of the event, an end time of the event, a description of the event, a status of the event, whether the event is to be repeated and the persons attending the event.

A useful parallel may be drawn with the way in which a walk is devised: possible tracks are explored, and may either prove intractable or interesting but potentially not consistent with the vision of the walk as-of-now being planned. From a traditional programming perspective, the development script is an unnecessarily complex object. The multiple definitions of observables, functions and procedures are an annoyance, as it can be hard to identify which definition is the last / most topical. Many EM developers have preferred to use traditional forms of version control in conjunction with a conventional file system to record development and versions. Loading a file of definitions is different in character from developing these definitions in the stream of thought. The process of reflection that accompanies construction is potentially very significant and fruitful, and is of the essence in EM. The premise of the SEEM is that the development script is an object to be preserved rather than ...

The human FFA was first described by Justine Sergent in 1992[2] and later named by Nancy Kanwisher in 1997[1] who proposed that the existence of the FFA is evidence for domain specificity in the visual system. Studies have recently shown that the FFA is composed of functional clusters that are at a finer spatial scale than prior investigations have measured.[3] Electrical stimulation of these functional clusters selectively distorts face perception, which is causal support for the role of these functional clusters in perceiving the facial image.[4] While it is generally agreed that the FFA responds more to faces than to most other categories, there is debate about whether the FFA is uniquely dedicated to face processing, as proposed by Nancy Kanwisher and others, or whether it participates in the processing of other objects. The expertise hypothesis, as championed by Isabel Gauthier and others, offers an explanation for how the FFA becomes selective for faces in most people. The expertise ...
Frequencies of occurrence of low-level image features is the representation of choice in the design of state-of-the-art visual object recognition systems. A crucial step in this process is the construction of a codebook of visual features, which is usually done by cluster analysis of a large number of low-level image features detected as interest points. However, clustering is a process that retains regions of high density in a distribution and it follows that the resulting codebook need not have discriminant properties. Here we extend our recent work on constructing a one-pass discriminant codebook design procedure inspired by the resource allocating network model from the artificial neural networks literature. Unlike clustering, this approach retains data spread out more widely in the input space, thereby including rare low-level features in the codebook. It simultaneously achieves increased discrimination and a drastic reduction in the computational needs. We illustrate some properties of our ...
Several brain regions have been linked to human face processing, most prominently the fusiform face area (FFA) in the fusiform gyrus. Dedicated architecture for face processing has also consistently been suggested by functional neuroimaging and single-unit recordings in primates. Faces are distinctive stimuli; they are a vital part of social interactions. Faces also are processed more holistically than other objects; face features and the relationships between them tend to be encoded all at once. Studies with infants and twins suggest a potential genetic component for specialized face processing. Such observations have led to the hypothesis that the FFA is an innate/dedicated face-processing area (i.e., the face-specificity hypothesis).. On the other hand, we are highly practiced at face recognition, as we must recognize associates among highly similar individuals. Also, experience appears to tune our ability to recognize different faces; people are generally better at recognizing faces of the ...
Are face parts and face configurations represented by a single neural population in the FFA, or does the FFA contain distinct neural populations, one responsive only to face parts and another responsive only to face configurations? To test these two alternatives, we used multivoxel pattern analysis to compare the similarity between the spatial activation pattern of face configurations and that of face parts. Specifically, a t value was extracted for the configural effect (stimuli with face configurations-stimuli without) and the featural effect (stimuli with face parts-stimuli without) for each voxel within the FFA in each subject, and then a correlation between these two sets of t values was calculated, separately for each subject. The correlation score of the right FFAs spatial activation patterns of two effects from a representative subject is shown in Figure 4A (r = .29, p , .001). To check further the distribution of r values against chance, we used a permutation test that randomly ...

Face perception is a microcosm of object recognition processes. The most difficult challenge in object recognition-distinguishing among similar visual forms despite substantial changes in appearance arising from changes in position, illumination, occlusion, etc.-is something we can do effortlessly for faces. Although face identification is often singled out as demanding particular sensitivity to differences between objects sharing a common basic configuration, in fact, such differences must be represented in the brain for both faces and nonface objects. This chapter argues that understanding face processing will illuminate the general problem of visual object recognition. It begins by discussing the functional architecture of the temporal lobe, with a special focus on the architecture of the system of face-selective areas in macaques and humans. It then discusses the physiology of cells in the temporal lobe, with a focus on the response properties of face-selective cells. Finally, it discusses different
Despite the computational difficulty, adults easily recognize faces with incredibly high sensitivity and specificity across novel changes in viewing conditions. Mature face representations are invariant to identity-preserving changes (e.g., changes in expression or viewing angle) while intolerant to identity-transforming changes (e.g., changes in texture, age, and gender). Yet, due to constraints in testing newborn subjects, the origins of these characteristics remain unknown. Are highly sensitive, specific, and generative face representations the product of extensive visual experience, or do genes build neural machinery that generates sensitive, specific, and generative face representations from the onset of experience with faces? To probe the nature of the first face representation created in the newborn mind, we reared newborn chickens for one week in a virtual reality chamber that contained no objects except a single virtual human face (the Virtual Parent). Immediately after, the chickens ...

Visualizations are one type of external representation that can be used to support sensemaking activities. In this paper, we investigate the role of two design strategies in making the interactive features of visualizations more supportive of users exploratory needs when trying to make sense of complex objects. These two strategies are visibility and complementarity of interactions. We employ a theoretical framework concerned with human-information interaction and complex cognitive activities to inform, contextualize, and interpret the effects of the design strategies. The two strategies are incorporated in the design of Polyvise, a visualization tool that supports making sense of complex four-dimensional geometric objects. A mixed-methods study was conducted to evaluate the design strategies and the overall usability of Polyvise. We
First, how do we know what animals remember? One way to test memory in rats is by using object recognition. You present the rat with two identical objects and let the animal explore them for a few minutes. Then you replace one of the objects with a new object, and typically, the rat will spend more time exploring the new object than the old one (presumably because the rat remembers the old one). By testing rat visual memory performance using this simple paradigm, the researchers established that rats were able to retain information about an object for up to 45 minutes, but after 60 minutes the objects were forgotten and treated as new unknowns. The researchers then injected a special protein in a specific part of the rats visual cortex, a part of the brain that is important for processing visual information. Following the injection, the rats were tested again for object recognition, and low and behold, the rats were now able to remember object information for longer than 45 minutes. How much ...
Texture informs our interpretation of the visual world. It provides a cue to the shape and orientation of a surface, to segmenting an image into meaningful regions, and to classifying those regions, e.g. in terms of material properties. This chapter discusses recent advances in understanding of segmentation and representation of visual texture. Successful models have described texture by a rich set of image statistics (stuff) rather than by the features of discrete, pre-segmented texture elements (things). Texture processing mechanisms may also underlie important phenomena in peripheral vision known as crowding. If true, such mechanisms would influence the information available for object recognition, scene perception, and many visual-cognitive tasks. ...

A deferred graphics pipeline processor comprising a texture unit and a texture memory associated with the texture unit. The texture unit applies texture maps stored in the texture memory, to pixel fragments. The textures are MIP-mapped and comprise a series of texture maps at different levels of detail, each map representing the appearance of the texture at a given distance from an eye point. The texture unit performs tri-linear interpolation from the texture maps to produce a texture value for a given pixel fragment that approximates the correct level of detail. The texture memory has texture data stored and accessed in a manner which reduces memory access conflicts and thus improves throughput of said texture unit.
Intrinsic uncertainty arises from sources intrinsic to the observer, in particular from the observers inability to attend to only the relevant information (attention limitations) and inability to remember the set of possible stimuli (memory limitations). This intrinsic uncertainty can be incorporated into the models based on multiple independent analyzers that were presented in the previous chapter for cases of extrinsic uncertainty. This chapter considers the interaction of uncertainty assumptions with the transducer function (output versus input function) of individual analyzers; the overall transducer function of all the analyzers used by the decision rule; the psychometric function for the observer; and the ROC curves. The control of attention and individual differences is discussed. ...

Disclosed is an apparatus comprising a jitter buffer that writes and reads packets transmitted via a packet network from a transmission node, a clock correction unit that obtains an inter-packet jitter, based on difference information between time stamp information at the time of reception of the packet on a receiving side and time stamp information attached to the packet at the time of transmission of the packet by a transmission node with regards to packets received before and after and obtains a transmission frequency and a PLL unit that receives frequency information from the clock correction unit and generates a clock of the frequency. A scheduler uses a frequency from the PLL unit as a transmission frequency to transmit a packet from the jitter buffer unit.
A method and system for rendering a desktop on a computer using a composited desktop model operating system are provided. A composited desktop window manager, upon receiving base object and content object information for one or more content objects from an application program, draws the window to a buffer memory, and takes advantage of advanced graphics hardware and visual effects to render windows based on content on which they are drawn. The frame portion of each window may be generated by pixel shading a bitmap having the appearance of frosted glass based on the content of the desktop on top of which the frame is displayed. Legacy support is provided so that the operating system can draw and render windows generated by legacy applications to look consistent with non-legacy application windows.

Herrnstein and Loveland (1964, pp. 549-551) successfully trained pigeons to discriminate pictures showing humans from pictures that did not. In the present study, a go/no-go procedure was employed to replicate and extend their findings, the primary focus of concern being to reevaluate the role of item- and category-specific information. The pigeons readily acquired the discrimination and were also able to generalize to novel instances of the two classes (Experiment 1). Classification of scrambled versions of the stimuli was based on small and local features, rather than on configural and global features (Experiment 2). The presentation of gray-scale stimuli indicated that color was important for classifying novel stimuli and recognizing familiar ones (Experiments 1 and 2). Finally, the control that could possibly be exerted by irrelevant background features was investigated by presenting the pigeons with images of persons contained in former person-absent pictures (Experiment 3). Classification ...

When constructing a line segment, we use a compass and straightedge to first draw a ray or line and then a point that will serve as an endpoint of the new segment. Next, we measure the given segment with a compass and make a mark with the pencil end. Without changing the spacing of the compass, place the sharp end of the compass on the point drawn on the new line/ray, and make a mark on the line/ray. This is our line segment.(2:02) ...

This is the unique object identifier for the object being processed. Every object is assigned an integer value that is unique among all objects in the simulation for all time. Even if an object is deleted, its identifier is never reused. The object identifier can always be used to uniquely identify a given object. This makes this variable very useful in situations where each object needs to be treated differently. It can be used to produce a unique random number for each object, for example. This value is also the best way to look up information on an object using the dopfield expression function. This value will be -1 if the node does not process objects sequentially (such as the ...
