Temporal aspects of stereoscopic slant estimation: an evaluation and extension of Howard and Kaneko's theory. (1/1300)

We investigated temporal aspects of stereoscopically perceived slant produced by the following transformations: horizontal scale, horizontal shear, vertical scale, vertical shear, divergence and rotation, between the half-images of a stereogram. Six subjects viewed large field stimuli (70 degrees diameter) both in the presence and in the absence of a visual reference. The presentation duration was: 0.1, 0.4, 1.6, 6.4 or 25.6 s. Without reference we found the following: rotation and divergence evoked considerable perceived slant in a number of subjects. This finding violates the recently published results of Howard and Kaneko. Slant evoked by vertical scale and shear was similar to slant evoked by horizontal scale and shear but was generally less. With reference we found the following: vertical scale and vertical shear did not evoke slant. Slant due to rotation and divergence was similar to slant due to horizontal scale and shear but was generally less. According to the theory of Howard and Kaneko, perceived slant depends on the difference between horizontal and vertical scale and shear disparities. We made their theory more explicit by translating their proposals into linear mathematical expressions that contain weighting factors that allow for both slant evoked by rotation or divergence, subject-dependent underestimation of slant and other related phenomena reported in the literature. Our data for all stimulus durations and for all subjects is explained by this 'unequal-weighting' extension of Howard and Kaneko's theory.  (+info)

Monocular occlusion cues alter the influence of terminator motion in the barber pole phenomenon. (2/1300)

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)

The effects of contrast on perceived depth and depth discrimination. (3/1300)

The contrast dependence of perceived depth was quantified through a series of depth matching experiments. Perceived depth was found to be a power law function of contrast. In addition, subjects exhibited a large uncrossed depth bias indicating that low contrast test patterns appeared much farther away than high contrast patterns of equal disparity. For disparities in the range of +/- 4.0 arc min, matching disparities for low contrast patterns were shifted in the uncrossed direction by the same amount. In other words, while the magnitude of the uncrossed depth bias is a power law function of contrast, it is constant with respect to disparity. In a second series of experiments, the contrast dependence of stereo increment thresholds was measured. Like perceived depth and stereoacuity, stereo increment thresholds were found to be a power law function of contrast. These results suggest that contrast effects occur at or before the extraction of depth and have implications for the response properties of disparity-selective mechanisms.  (+info)

Quantitative depth for a phantom surface can be based on cyclopean occlusion cues alone. (4/1300)

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)

Configuration saliency revealed in short duration binocular rivalry. (5/1300)

Supra-threshold spatial integration was studied by testing the saliency of multi-Gabor element configurations in short duration binocular rivalry (dichoptic masking) conditions. Dichoptic presentations allow for a competition between spatially overlapping supra-threshold stimuli that involve non-overlapping monocular receptive fields in the first stage of visual filtering. Different spatial configurations of Gabor patches (sigma = lambda = 0.12 degree) were presented to one eye (target) together with a bandpass noise presented to the other eye (mask). After a short rivalry period (120 ms) in which a dominance of one eye was established, a probe (a randomly positioned small rectangle of reduced contrast in the target) was presented for additional detection period (80 ms). Probe detection performance was measured (two-alternative-forced choice paradigm (2AFC) by finding the mask contrast leading to 79% correct response. Results show that configuration saliency is consistently expressed as dominance in short-duration binocular rivalry, with similar results obtained for longer durations (200 ms and continuous presentations). We find that textures of high-contrast randomly oriented patches are more dominant than uniform textures where the effect decreases and eventually reverses with decreasing of contrast. For supra-threshold contours, however, we find that smooth collinear contours are more dominant than 'jagged' ones, regardless of phase and contrast. These findings suggest principles underlying early lateral integration mechanisms based on contrast dependent inhibitory and excitatory connections. This mechanism could be based on iso-orientation surround (2D) inhibition and collinear (1D) facilitation, with inhibition being more effective at high contrasts.  (+info)

Occlusion contributes to temporal processing differences between crossed and uncrossed stereopsis in random-dot displays. (6/1300)

Stereoscopic depth discrimination was investigated in crossed and uncrossed directions using stimuli defined by binocular disparity differences embedded in dynamic random-dot stereograms. Across three experiments, fixation was directed to a point on the display screen (which placed crossed stimuli in front of and uncrossed stimuli behind, the background dots of the stereogram), to a point in front of the display screen (which placed both crossed and uncrossed stimuli in front of the background dots), and to a point behind the display screen (which placed both crossed and uncrossed stimuli behind the background dots). Results showed that depth discrimination was always good when the stimuli appeared in front of the background dots of the stereogram, whereas discrimination was always poor when the stimuli appeared behind the background dots. These results suggest that differences between crossed and uncrossed stereopsis as reported in past research arose, in part, from effects related to occlusion.  (+info)

Categorical learning in pigeons: the role of texture and shape in complex static stimuli. (7/1300)

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)

Feature specific segmentation in perceived structure-from-motion. (8/1300)

Motion information is important to vision for extracting the 3-D (three-dimensional) structure of an object, as evidenced by the compelling percept of three-dimensionality attainable in displays which are purely motion-defined. It has recently been shown that when subjects view a rotating transparent cylinder of dots simulated with parallel projection, they rarely perceive rotation reversals which are physically introduced (Treue, Andersen, Ando & Hildreth, Vision Research, 35;1995:139-148). We show however that when the elements defining the cylinder are oriented, the number of perceived reversals increases systematically to near maximum as the difference between element orientations on the two surfaces increases. These results imply that structure-from-motion mechanisms are capable of exploiting local feature differences between the different surfaces of a moving object.  (+info)

Stereoscopic depth perception is based on binocular disparities. Although neurons in primary visual cortex (V1) are selective for binocular disparity, their responses do not explicitly code perceived depth. The stereoscopic pathway must therefore include additional processing beyond V1. We used functional magnetic resonance imaging (fMRI) to examine stereo processing in V1 and other areas of visual cortex. We created stereoscopic stimuli that portrayed two planes of dots in depth, placed symmetrically about the plane of fixation, or else asymmetrically with both planes either nearer or farther than fixation. The interplane disparity was varied parametrically to determine the stereoacuity threshold (the smallest detectable disparity) and the upper depth limit (largest detectable disparity). fMRI was then used to quantify cortical activity across the entire range of detectable interplane disparities. Measured cortical activity covaried with psychophysical measures of stereoscopic depth perception.

We explore the relative utility of shape from shading and binocular disparity for depth perception. Ray-traced images either featured a smooth surface illuminated from above (shading-only) or were defined by small dots (disparity-only). Observers judged which of a pair of smoothly curved convex objects had most depth. The shading cue was around half as reliable as the rich disparity information for depth discrimination. Shading- and disparity-defined cues where combined by placing dots in the stimulus image, superimposed upon the shaded surface, resulting in veridical shading and binocular disparity. Independently varying the depth delivered by each channel allowed creation of conflicting disparity-defined and shading-defined depth. We manipulated the reliability of the disparity information by adding disparity noise. As noise levels in the disparity channel were increased, perceived depths and variances shifted toward those of the now more reliable shading cue. Several different models of cue ...
The identification of brain regions that are associated with the conscious perception of visual stimuli is a major goal in neuroscience. Here we present a test of whether the signals on neurons in cortical area V1 correspond directly to our conscious perception of binocular stereoscopic depth. Depth perception requires that image features on one retina are first matched with appropriate features on the other retina. The mechanisms that perform this matching can be examined by using random-dot stereograms, in which the left and right eyes view randomly positioned but binocularly correlated dots. We exploit the fact that anticorrelated random-dot stereograms (in which dots in one eye are matched geometrically to dots of the opposite contrast in the other eye) do not give rise to the perception of depth because the matching process does not find a consistent solution. Anti-correlated random-dot stereograms contain binocular features that could excite neurons that have not solved the correspondence problem.

In an automotive contact analog head-up display (cHUD), virtual information can be presented in augmented reality manner in the drivers primary field of view, minimizing mental transformation effort for the driver. Whether virtual information in the cHUD is really perceived at the correct location in the environment depends on several factors such as the technological specifications of the cHUD, the design of the virtual information or environmental conditions. One possibility to realize a cHUD is to implement an upright virtual image in a distance at which human depth perception is supposed to rely on monocular depth cues only (, 6m). So far it has not been investigated whether this technology succeeds at conveying the correct spatial impression of the virtual information to the driver. In the current study, we investigated whether depth perception of lying navigation arrows in a cHUD with a fixed virtual image distance of 10m was influenced by (a) whether the arrow was overlaid on the road ...
Sports fans have come to expect some of the extras they see on their TV screen, such as the yellow lines that appear on a football field to highlight where the ball needs to go for a first down. Augmented reality, or AR, is used to superimpose computer-generated virtual objects on our view of the real world. With support from the National Science Foundation, Mississippi State University (MSU) researchers are working to improve depth perception in the augmented reality environment. One challenge is aligning an object in the real word so that it precisely lines up with virtual objects. Accurate depth perception is critical to medical and military applications of augmented reality.

I had a weird misconception about stereoscopic vision when I was younger, which is that without it the world is some sort of crazy Picassoland devoid of perspective and 3-dimensional space. I was so confused as a kid after wandering around with one eye closed to find that everything looked dissapointingly similar. This in turn led me to think that maybe I was different, maybe I didnt have correct stereoscopic vision and other strange conclusions. It wasnt until I was randomly forced to spend a couple days with only one contact in rather than both that started to notice differences. It doesnt really affect perception much at all, but processing tasks (as many who cannot see stereoscopically have commented already). Anything that requires you to unconsciously and quickly calculate distance is impossibly harder. To me the difference is closer to comparing a pro athlete with an amateur ...
The image formed on the retina of a single eye contains no information about the distance of objects. After all, a retina image is a two-dimensional projection of the outside world. Nevertheless, even with the use of one eye, conclusions can be made about distance based upon perspective: the angle at which objects of known size are observed and the partial masking of distant objects by objects that are closer to us. The fact that our spatial awareness hardly changes when we use only one eye is the best proof of the effectiveness of this capability.. However, to determine very small relative distance differences, people are dependent on the use of information derived from two eyes. Stereopsis, also known as stereoscopic depth perception or binocular parallax, is the ability of both eyes to see the same object as one image and to create a perception of depth. This parallax is a direct consequence of the fact that our eyes perceive the world from slightly different positions. Objects that are at ...
Desktop 3D displays vary in their optical design and this results in a significant variation in the way in which stereo images are physically displayed on different 3D displays. When precise depth judgements need to be made these differences may become critical to task performance. Applications where this is a particular issue include medical imaging, geoscience and scientific visualization. We investigate perceived depth thresholds for four classes of desktop 3D display; full resolution, row interleaved, column interleaved and colour-column interleaved. Given the same input image resolution we calculate the physical view resolution for each class of display to geometrically predict its minimum perceived depth threshold. To verify our geometric predictions we present the design of a task where viewers are required to judge which of two neighboring squares lies in front of the other. We report results from a trial using this task where participants are randomly asked to judge whether they can ...
A stereoscope required a special kind of dual photograph or stereo-pair painting. A number of artists, including Salvador Dali, created exceptional stereo-pair paintings for the stereoscope.. Around 1849-1850, David Brewster, a Scottish scientist, improved the Wheatstone stereoscope by using lenses instead of mirrors, thus reducing the size of the contraption. Brewster also noticed that staring at repeated patterns in wallpapers could trick the brain into matching pairs of them and thus causing the brain to perceive a virtual plane behind the walls. This is the basis of single-image wallpaper stereograms.. In 1959, Dr. Bela Julesz, a vision scientist, psychologist, and MacArthur Fellow, discovered the random-dot stereogram while working at Bell Laboratories on recognizing camouflaged objects from aerial pictures taken by spy planes. Dr. Julesz also invented the autostereogram as a definitive test of Binocular Depth perception. At the time, many vision scientists still thought that depth ...
Stereopsis recovery, also recovery from stereoblindness, is the phenomenon of a stereoblind person gaining partial or full ability of stereo vision (stereopsis). Recovering stereo vision as far as possible has long been established as an approach to the therapeutic treatment of stereoblind patients. Treatment aims to recover stereo vision in very young children, as well as in patients who had acquired but lost their ability for stereopsis due to a medical condition. In contrast, this aim has normally not been present in the treatment of those who missed out on learning stereopsis during their first few years of life. In fact, the acquisition of binocular and stereo vision was long thought to be impossible unless the person acquired this skill during a critical period in infancy and early childhood. This hypothesis normally went unquestioned and has formed the basis for the therapeutic approaches to binocular disorders for decades. It has been put in doubt in recent years. In particular since ...

There has been no direct examination of stereoscopic depth perception at very large observation distances and depths. We measured perceptions of depth magnitude at distances where it is frequently reported without evidence that stereopsis is non-functional. We adapted methods pioneered at distances up to 9 m by R. S. Allison, B. J. Gillam, and E. Vecellio (2009) for use in a 381-m-long railway tunnel. Pairs of Light Emitting Diode (LED) targets were presented either in complete darkness or with the environment lit as far as the nearest LED (the observation distance). We found that binocular, but not monocular, estimates of the depth between pairs of LEDs increased with their physical depths up to the maximum depth separation tested (248 m). Binocular estimates of depth were much larger with a lit foreground than in darkness and increased as the observation distance increased from 20 to 40 m, indicating that binocular disparity can be scaled for much larger distances than previously realized. Since these

Stereopsis (from the Greek στερεο- stereo- meaning solid, and ὄψις opsis, appearance, sight) is a term that is most often used to refer to the perception of depth and 3-dimensional structure obtained on the basis of visual information deriving from two eyes by individuals with normally developed binocular vision. Because the eyes of humans, and many animals, are located at different lateral positions on the head, binocular vision results in two slightly different images projected to the retinas of the eyes. The differences are mainly in the relative horizontal position of objects in the two images. These positional differences are referred to as horizontal disparities or, more generally, binocular disparities. Disparities are processed in the visual cortex of the brain to yield depth perception. While binocular disparities are naturally present when viewing a real 3-dimensional scene with two eyes, they can also be simulated by artificially presenting two different images ...

Stereopsis is an important binocular cue to depth perception. Stereopsis cannot occur monocularly and is due to binocular retinal disparity within Panums fusional space. Stereopsis is the perception of depth produced by binocular retinal disparity. Therefore, two objects stimulates disparate (non-corresponding) retinal points within Panums fusional area.. Fusion describes the neural process that brings the retinal images in the two eyes to form one single image. Fusion occurs to allow single binocular vision. Fusion takes place when the objects are the same. When the objects are different, suppression, superimposition or binocular (retinal) rivalry may occurs. Suppression occurs to eliminate one image to prevent confusion. Superimposition results in one image presented on top of the other image. Binocular rivalry describes alternating suppression of the two eyes resulting in alternating perception of the two images. This usually occurs when lines are presented to the two eyes differ in ...
Results Randot stereoacuity improved by an average of one plate (ie, one test level) on repeat testing but was little changed when tested on the third occasion. Within-subject variability was up to three test levels on repeat testing. When stereoacuity was categorised as fine, intermediate or coarse, the greatest variability was found among younger children who exhibited intermediate or coarse/nil stereopsis on initial testing. Whereas 90.8% of children with fine stereopsis (≤50 arc-seconds) on the first test exhibited fine stereopsis on both subsequent tests, only ∼16% of children with intermediate (,50 but ≤140 arc-seconds) or coarse/nil (≥200 arc-seconds) stereoacuity on initial testing exhibited stable test results on repeat testing. ...

There are at least two possible explanations for the difference between thresholds. First, a subjects sensitivity to test stimulus slant may be suppressed by the surface moving in the opposite direction in much the same depth plane. Alternatively, sensitivity to the test stimulus may be facilitated by a surface moving in the same direction at the same depth or with opposite direction in a different depth plane. To choose between these possibilities we needed a control measurement in which the test stimulus differed from both cylinder surfaces in either depth or velocity so that, as far as possible, sensitivity to the test stimulus was uninfluenced by the inducing stimulus. The control, consisting of the test stimulus located at the cylinders axis, yielded the thresholds shown on the right of Figure 2B. The confidence intervals show that the control measurements resulting from leftward and rightward stimulus movements were not significantly different, and the two measurements were therefore ...

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

Vergence is the motor ability that allows us to move our eyes to point them at the target. However, binocularity comes from the the sensory ability to interpret two images into one richer image. Each eye actually sees a slightly different image. The brain puts these images together and creates a 3D picture out of it by a process called fusion. If your eyes arent team players, it is difficult to judge depth, relationships, and other types of spatial awareness. If your eyes are not aligned well, your brain has a hard time fusing the two images, which can lead to double vision, confusion or ignoring an image (suppression). Think of a pair of binoculars. If you dont have the two oculars set up correctly, it doesnt feel good and it is hard to concentrate on what you are looking at, or judge where you are looking. When this happens, many people will ignore one eye and just use the other. The brain makes these types of compensations as well.. DEPTH PERCEPTION. Depth perception is the visual ability ...

abstract = {We present the in-situ visualization of medical data taken from CT or MRI scans in real-time using a video see-through head mounted display (HMD). One of the challenges to improve acceptance of augmented reality (AR) for medical purpose is to overcome the misleading depth perception. This problem is caused by a restriction of such systems. Virtual entities of the AR scene can only be presented superimposed onto real imagery. Occlusion is the most effective depth cue [3] and let e.g. a correctly positioned visualization of the spinal column appear in front of the real skin. We present a technique to handle this problem and introduce a Virtual Window superimposed onto the real skin of the patient to create the feeling of getting a view on the inside of the patient. Due to motion of the observer the frame of the window covers and uncovers fragments of the visualized bones and tissue and enables the depth cues motion parallax and occlusion, which correct the perceptive misinformation. An ...
When a person reaches out to place an object in just the right place, their mind makes a series of judgments requiring vision, stability and careful movement.
In relationships of all kinds, we practice diplomatic dishonesty in many different forms. Out of balance, diplomatic dishonesty becomes codependence, one of the most unhealthy types of controlling behavior, I think. It can also go out of balance in the other direction. I am no fan of radical honesty. Ive seen people use that excuse to say the most hurtful things you can imagine. Part of being two-eyed means we can think before we speak. Well, we can, even though sometimes its difficult. We can ask ourselves what we hope to accomplish by saying whatever it is thats tickling our throats, rattling the voicebox in its eagerness to get out. What I really dislike about radical honesty is the idea that we should never filter what we say. Should we say everything? To what end ...
I was in line at Publix the other night. Grabbing some chicken tenders at their deli, I needed to pay for the poultry and get back to work. The kid in the checkout was helping the customer in front of me, and in the back of my mind, Im sure I noticed the sweet track of music playing over the speaker system in the grocery: Seals Kiss From a Rose. What I then noticed was that as he was transitioning from ringing up the previous customer to ringing up my meal, he was mouthing words, while looking down. I thought, what is he saying? and who is he talking to? Then, to my horror and delight, I put 2 and 2 together. This young buck had Seal in his soul.

A Head-Up Display(HUD) is required that can give information to the driver in an easy to understand manner which can prevent traffic accidents. AR-HUDs are used to display driving information that overlay the image on the actual scenery. It is important for AR-HUDs to see the information and the actual scene at the same time and the depth feeling and the distance feeling are key factors. Binocular parallax used in stereoscopic 3D display is one of the most useful method to provide the depth feeling and the distance. In general, the stereoscopic 3D display sets the image range in the Panums fusional area to avoid inhibition of fusion. However, in the case of using the stereoscopic 3D display for AR-HUD, the image range must be set beyond the Panums fusional area to see the information and the actual scene at the same time. In this study, we were investigated the visibility of stereoscopic 3D display beyond the Panums fusional area for AR-HUDs. Easiness of fusion was measured by the ...
With the recent advancement in visualization devices over the last years, we are seeing a growing market for stereoscopic content. In order to convey 3D content by means of stereoscopic displays, one needs to transmit and display at least 2 points of view of the video content. This has profound implications on the resources required to transmit the content, as well as demands on the complexity of the visualization system. It is known that stereoscopic images are redundant which may prove useful for compression and may have positive effect on the construction of the visualization device. In this paper we describe an experimental evaluation of data redundancy in color stereoscopic images. In the experiments with computer generated and real life test stereo images, several observers visually tested the stereopsis threshold and accuracy of parallax measurement in anaglyphs and stereograms as functions of the blur degree of one of two stereo images. In addition, we tested the color saturation ...
