Geometric representation of the mechanisms underlying human curvature detection. (1/1967)

Combined manipulation of blur, line length and contrast reveal two distinct processes involved in curvature detection. When line length is small relative to blur, thresholds are almost directly proportional to blur and independent of line length. When line length is large relative to blur thresholds are directly proportional to line length and independent of blur. The aspect ratio (line length/blur) of curved contours represents a scale-invariant metric which forms the decisive factor in determining curvature performance.  (+info)

Orientation-tuned spatial filters for texture-defined form. (2/1967)

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)

Amodal completion in texture visual evoked potentials. (3/1967)

Amodal completion refers to the phenomenological finding of perceiving partly occluded objects as continuing uninterrupted behind an occluder. The outlying problem is how the visual system processes such non-local stimuli because the known processes of early vision are spatially restricted operations which segregate local differences in the visual image, and little is known about their interactions in producing the segmentation of the image into functionally coherent, or global, objects. We recorded human visual evoked potentials (VEPs) to texture stimuli and addressed local/non-local relationships in comparing a condition in which local edges were present, due to texture segregation, with a condition in which, in addition to local edges, textures appeared to continue as surfaces behind gray stripes due to non-local amodal completion. Subtraction of offset from onset responses showed: (1) a difference component due to texture segregation characterized by a negativity with onset at about 95 ms and lasting up to about 280 ms; (2) a further negativity, specifically elicited by amodal completion, with onset at about 142 ms, peaking at 175 ms, and lasting up to about 188 ms. Therefore, amodal completion occurs at an early processing stage of image analysis and the difference component in VEPs can be related to figure-ground perception.  (+info)

Quantitative depth for a phantom surface can be based on cyclopean occlusion cues alone. (4/1967)

Liu, L., Stevenson, S.B., and Schor, C.M. (1994, Nature, 367, 66-669) reported quantitative stereoscopic depth in a phantom rectangle which appeared to lack conventional matching elements. Later, Gillam, B.J. (1995, Nature, 373, 202-203) and Liu, L., Stevenson, S.B., and Schor, C.M. (1995, Nature, 373, 203) and Liu, L., Stevenson, S.B., and Schor, C.M. (1997, Vision Research, 37(5), 633-644) indicated that the varying depth of the phantom rectangle could be based on stereoscopic matching. To remove the contaminating effects of conventional stereopsis from the Liu et al. (1994) original example, we presented a pair of parallel vertical lines to each eye where there is a central gap in the right line for the left eye's view and in the left line for the right eye's view. Observers saw a phantom rectangle bounded by subjective contours whose depth increased with the thickness of the lines. We attribute the quantitative variation of depth to a purely cyclopean (binocular) process sensitive to the pattern of contour presence and absence in the two eye's view.  (+info)

Role of feedback in mammalian vision: a new hypothesis and a computational model. (5/1967)

This paper presents a novel hypothesis on the function of massive feedback pathways in mammalian visual systems. We propose that the cortical feature detectors compete not for the right to represent the output at a point, but for exclusive rights to abstract and represent part of the underlying input. Feedback can do this very naturally. A computational model that implements the above idea for the problem of detection is presented and based on that we suggest a functional role for the thalamo-cortical loop during perception of lines. We show that the model successfully tackles the so called Cross problem. Based on some recent experimental results, we discuss the biological plausibility of our model. We also comment on the relevance of our hypothesis (on the role of feedback) to general sensory information processing and recognition.  (+info)

Synchronization between temporal and parietal cortex during multimodal object processing in man. (6/1967)

A series of recordings in cat visual cortex suggest that synchronous activity in neuronal cell ensembles serves to bind the different perceptual qualities belonging to one object. We provide evidence that similar mechanisms seem also to be observable in human subjects for the representation of supramodal entities. Electroencephalogram (EEG) was recorded from 19 scalp electrodes (10/20 system) in 19 human subjects and EEG amplitude and coherence were determined during presentation of objects such as house, tree, ball. Objects were presented in three different ways: in a pictorial presentation, as spoken words and as written words. In order to find correlates of modality-independent processing, we searched for patterns of activation common to all three modalities of presentation. The common pattern turned out to be an increase of coherence between temporal and parietal electrodes in the 13-18 Hz beta1 frequency range. This is evidence that population activity of temporal cortex and parietal cortex shows enhanced coherence during presentation of semantic entities. Coherent activity in this low-frequency range might play a role for binding of multimodal ensembles.  (+info)

Visual form created solely from temporal structure. (7/1967)

In several experiments, it was found that global perception of spatial form can arise exclusively from unpredictable but synchronized changes among local features. Within an array of nonoverlapping apertures, contours move in one of two directions, with direction reversing randomly over time. When contours within a region of the array reverse directions in synchrony, they stand out conspicuously from the rest of the array where direction reversals are unsynchronized. Clarity of spatial structure from synchronized change depends on the rate of motion reversal and on the proportion of elements reversing direction in synchrony. Evidently, human vision is sensitive to the rich temporal structure in these stochastic events.  (+info)

Categorical learning in pigeons: the role of texture and shape in complex static stimuli. (8/1967)

Pigeons are known to be able to categorize a wide variety of visual stimulus classes. However, it remains unclear which are the characteristics of the perceptually relevant features employed to reach such good performance. Here, we investigate the relative contributions of texture and shape information to categorization decisions about complex natural classes. We trained three groups of pigeons to discriminate between sets of photorealistic frontal images of human faces according to sex and subsequently, tested them on different stimulus sets. Only the pigeons that were presented with texture information were successful at the discrimination task. Pigeons seem to possess a sophisticated texture processing system but are less capable in discriminating shapes. The results are discussed in terms of the possible evolutionary advantages of utilizing texture as a very general and potent perceptual dimension in the birds' visual environment.  (+info)

Automated Method and System for the Segmentation of Lung Regions in Computed Tomography Scans A method and system for the automated segmentation of the lung regions in thoracic CT scans includes construction of a cumulative gray level profile from pixels along the diagonal of each CT section image. The shape of this profile is used to identify a gray level threshold that is used to create a binary image. A contour detection algorithm generates a segmented thorax region. The trachea and main bronchi are segmented and eliminated from the segmented thorax region to prevent subsequent inclusion within the segmented lung regions. A gray level histogram is constructed to identify a second gray level threshold, which is applied to the segmented thorax region to create a binary image. If the two lungs regions are
An improved apparatus and method for forming a three-dimensional object by planar deposition of forming materials includes containers for holding molten forming materials, mechanical piston or screw members in the containers for pressurizing the molten forming materials in each of the containers, and an adjustable planar nozzle mechanism coupled to the containers through which the pressurized molten forming materials flow to form variable width planar jets that are deposited in layers onto a substrate movable along three axes to form the three-dimensional object. The adjustable planar nozzle mechanism includes cooperating position controllable plates for forming a variable width planar nozzle opening. The edges of the planar nozzle opening are advantageously non-parallel at the ends of the nozzle opening to ensure uniform thickness of the deposited planar jets.

Since the texture inside an uncamouflaged objects boundary is often different to the texture outside, it would seem undesirable to integrate texture modulation across the border. In order to see if the visual system is able to be selective, we used RF textures divided into inner and outer regions, and used a readily detectable contour to segment the regions in some instances, so that we could characterize the effect of texture differences and also that of segmenting contours. An area of texture was split into two regions; the regions were matched such that they were of equal area. Modulation was manipulated such that it either appeared only in the Inner, Outer, or in Both regions. For modulation that appeared in the Inner and Outer regions, their respective outer and inner regions were filled with nonmodulated circular texture. Potentially when one texture is surrounded by another area of differing texture, the surrounded area can appear to perceptually pop out. This is known as texture ...

To assess the influence of attention on the amplitude and timing of brain responses involved in figure versus background processing, participants were instructed to fixate on a fixation mark at the center of the display and perform one of two different tasks in separate experimental blocks. In the Shape Discrimination trials, the observers indicated a change in the shape of the figure with a button press (see Figure 1b). On 20% of the 1.67-second stimulus cycles, the aspect ratio (horizontal to vertical) of the figure became elliptical (,1). Responses were monitored and the figure aspect ratio was adjusted to maintain performance at approximately 80% correct detection. In the Letter Detection trials, the observers were instructed to attend to a stream of simultaneously presented letters and to detect a probe letter T among distracters L (see Figures 1c and 1d). Letter arrays containing Ls and Ts appeared superimposed upon the figure region of the stimulus and were preceded and followed ...
The diffogram, which is shown to the right (click to enlarge), is my favorite graph for multiple comparisons of means. Every diffogram displays a diagonal reference line that has unit slope. Horizontal and vertical reference lines are placed along the axes at the location of the means of the groups. For these data, there are four vertical and four horizontal reference lines. At the intersection of most reference lines there is a small colored line segment. These segments indicate which of the 4(4-1)/2 = 6 pairwise comparisons of means are significant. Lets start at the top of the diffogram. The mean for the Caldecot site is about 0.3, as shown by a horizontal reference line near Y=0.3. On the reference line for Caldecot are three line segments that are centered at the mean values for the other groups, which are (from left to right) IslandThorns, AshleyRails, and Llanederyn. The first two line segments (in blue) do not intersect the dashed diagonal reference line, which indicates that the means ...
This video explains how to construct a line segment. 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) ...

Purpose: : Recent progress in understanding the pathogenesis of macular degeneration has led to potential new treatments for the disease. There is an increasing demand for new visual function tests that are more sensitive than current standards to monitor disease progression and to evaluate treatment effect. Our previous studies demonstrated that patients with macular degeneration have significant loss in global shape discrimination hyperacuity. In this study, we determined the rate of progressive loss of this hyperacuity in patients with Stargardt macular dystrophy (STGD). Methods: : Sixty-eight patients with STGD were selected on the basis of 20/200 or better visual acuity in at least one eye at their first visit. The average age at the first visit was 33±15SD years, and the average follow-up was 4.3±2.8SD years. Visual stimuli were circular shapes (radial frequency patterns). Shape discrimination hyperacuity was determined by using a two-alternative forced-choice paradigm. Each trial ...

A surface shape recognition apparatus includes detection circuit, comparison circuit, storage circuit, and control circuit. The detection circuit electrically detects a surface shape pattern in a partial region of the target collation surface of an object using a plurality of sensor elements and outputs detection data representing the surface shape pattern. The comparison circuit compares the detection data from the detection circuit with predetermined collation data and outputs a comparison result. The storage circuit stores template data representing the surface shape pattern of the entire target collation surface, the template data being obtained from the object in advance. The control circuit partially reads out, as collation data, the template data stored in the storage circuit from an arbitrary position, outputs the collation data to the comparison circuit, and performs determination for authentication between the template data and the object on the basis of the comparison result from the
BACKGROUND: The perception of global form requires integration of local visual cues across space and is the foundation for object recognition. Here we used magnetoencephalography (MEG) to study the location and time course of neuronal activity associated with the perception of global structure from local image features. To minimize neuronal activity to low-level stimulus properties, such as luminance and contrast, the local image features were held constant during all phases of the MEG recording. This allowed us to assess the relative importance of striate (V1) versus extrastriate cortex in global form perception. METHODOLOGY/PRINCIPAL FINDINGS: Stimuli were horizontal, rotational and radial Glass patterns. Glass patterns without coherent structure were viewed during the baseline period to ensure neuronal responses reflected perception of structure and not changes in local image features. The spatial distribution of task-related changes in source power was mapped using Synthetic Aperture Magnetometry
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.
The human visual system seems to be equipped with mechanisms to establish whether or not a two-dimensional image represents a view of a structurally possible three-dimensional object. An example is provided by the so-called impossible objects, first described by Penrose & Penrose [1]. These consist of two-dimensional figures at first perceived as representing a projection of a three-dimensional object, but then immediately and effortlessly recognized as an object that cannot actually exist in the form interpreted by the visual system.. Several local cues need to be integrated to detect global inconsistencies in structural information, allowing discrimination between possible and impossible objects; a long-standing debate exists as to the role played by experience with real three-dimensional objects in the development of these abilities [2,3].. Recently, Shuwairi et al. [4] reported that four-month-old infants can discriminate between structurally possible and impossible objects. However, four ...
An apparatus for producing a three-dimensional object by successive solidification of layers of a powder material at points corresponding to a cross-section of said object using electromagnetic or particle radiation comprises support means having an upper side for supporting the object thereon at a determined elevation, elevation adjustment means for varying the elevation, means for applying a layer of the material onto the upper side or onto another layer formed on the upper side, and irradiation means for irradiating the layer of the material at the points corresponding to a cross-section of the object. For reducing the production time of the object the apparatus further comprises a prefabricated base plate on the upper side, the base plate being made of a material which the powder material adheres to when being solidified, and means for removably connecting the base plate to the upper side of the support means.

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.

In this way, it is possible to calculate the AUC by using an average of a number of trapezoidal approximations. It is also common to calculate the Area Under the ROC Convex Hull (ROC AUCH = ROCH AUC) as any point on the line segment between two prediction results can be achieved by randomly using one or other system with probabilities proportional to the relative length of the opposite component of the segment.[17] It is also possible to invert concavities - just as in the figure the worse solution can be reflected to become a better solution; concavities can be reflected in any line segment, but this more extreme form of fusion is much more likely to overfit the data.[18] The machine learning community most often uses the ROC AUC statistic for model comparison.[19] This practice has recently been questioned because AUC estimates are quite noisy and suffers from other problemns.[20] [21][22]. Nonetheless, the coherence of AUC as a measure of aggregated classification performance has been ...

Of the presently available methods for segmentation of anatomic objects from medical images, principally interactive ones are the most commonly used in clinical practice. More automatic techniques are based on statistical pattern recognition (thresholding), mathematical morphology, deformable models with local geometric constraints (active surfaces), or deformable structural models, i.e., using models that involve nonlocal spatial relationships. The methods involving the deformation of structural models seem distinctly the most successful, and they lend themselves not only to segmentation but also to shape measurement and registration. It is on these that we focus. Access to our papers on object segregation and shape representation, subdivided into topic areas, can be made through the Bibliography page.

Several methods for vanishing point detection make use of the line segments detected in images. Other techniques involve considering the intensity gradients of the image pixels directly. There are significantly large numbers of vanishing points present in an image. Therefore, the aim is to detect the vanishing points that correspond to the principal directions of a scene. This is generally achieved in two steps. The first step, called the accumulation step, as the name suggests, clusters the line segments with the assumption that a cluster will share a common vanishing point. The next step finds the principal clusters present in the scene and therefore it is called the search step. In the accumulation step, the image is mapped onto a bounded space called the accumulator space. The accumulator space is partitioned into units called cells. Barnard [4] assumed this space to be a Gaussian sphere centered on the optical center of the camera as an accumulator space. A line segment on the image ...

3. Students begin by placing their ships in either 2 dot line segment, 3 dot line segment, and 4 dot line segment. Students can use the TalkingBrix 2 and Step-by-Step to assist with placement by giving coordinates (ex. the coordinate (-3,2) would be given by hitting the TalkingBrix 2 to say the number is negative, then step through the Step-by-Step until the number 3 is reached. For the number 2, the student will cycle through the Step-by-Step until they come to the number 2 ...
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.

In order to fully excavate the information contained in the multi-index panel data, one take decision objects as the research object, and the development state matrix and the development speed matrix of the decision objects are defined by considering the cross-section information and time information of the decision objects, and then the distances among the objects over the indexes are given. Based on grey incidence analysis, the absolute difference and relative difference between the measure value matrices are used to characterize and measure the close degree of the development state matrix and the development level matrix of the decision objects, so that the grey object matrix absolute incidence analysis model is established, and then according to the grey incidence degree between the objects, the objects can be clustered based on hierarchical clustering algorithm. Finally, a clustering problem of regional patent research and development (R&D) efficiency is used to verify the validity and rationality
Different objects within the same exhibit may require different rotation schedules. While the benefit of imposing one schedule is clear, the display period for objects that are highly sensitive should not be extended to coincide with rotation of other objects that can remain on exhibit for longer time periods. A successful strategy for some museums has been to remove sensitive materials from display during periods of low visitation, which may account for periods of up to 6 months of each year. ...
I have found the stress test concept not simply a sham but a sinister capitulation by the government to the bankers. The real function of these tests, to me, is not in any way to find out or even to shape perceptions of the _banks_, it is to give the traitors running government financial policy political cover to shovel more money faster to the corrupt financial institutions which are chewing the face off our republic of laws. The tests show that what the government is doing to this point is working, i.e. the banks are getting by. What is needed by that image is, more of the same only moreso. Far from testing the banks, this exercise in perverse performance art is designed to sell the Stealout to the media and Congress. I use the word traitors advisedly. To this point, one could argue that folks like Geithner and Summers were ill-conceived in their actions. Too friendly to those who their policies are enriching with public money. Even corrupt in their tireless efforts to reward their ...

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 ...

From the previous objective you might expect that the first output Equal without new operator would never be seen as s and s2 are different objects, and the == operator tests what an object points to, not its value. However because of the way Java conserves resources by re-using identical strings that are created without the new operator s and s2 have the same address and the code does output the string Equal without new operator. However with the second set of strings t and u, the new operator forces Java to create separate strings. Because the == operator only compares the address of the object, not the value, t and u have different addresses and thus the string Equal with new operator is never seen.. ...
