In this work the range and scaling properties of the cooperative (contextual) interaction that was first proposed by Julesz [Foundations of Cyclopean Perception, University of Chicago Press, Chicago, 1971] to address the correspondence problem in stereopsis is measured. To this end the effect that flanking difference of Gaussians (DoG) patches produce on a perception of a target pair of patches...

PURPOSE To determine what critical immaturity is responsible for the poor binocular stereopsis of human infants. METHODS Infant and adult psychometric functions were measured for detection of stereoscopic depth in a random-texture display. A test stimulus defined by horizontal binocular disparity and a distracter stimulus defined by vertical disparity were used. Adults were tested by direct p...

In this paper, we propose systems which can render free viewpoint images by using depth image based rendering for live video communications. Experimental results show that an image and depth transmission system is more suitable than an all multi view transmission and an only free viewpoint image transmission system. Especially in the image and depth transmission system, transmitting two images ...

The need for routine amblyopia screening of all children, making such screening "as important a part of medical care as immuni­ zations," is all but self-evident. Although, as Lippman points out, many of the traditional incidence statistics need interpretation to be meaningful, most recent large-scale screening efforts of children indicate an amblyopia in­ cidence of 1 to 3 % in the general pop...

There is a long history of research into depth percepts from very large disparities, beyond the fusion limit. Such diplopic stimuli have repeatedly been shown to provide reliable depth percepts. A number of researchers have pointed to differences between the processing of small and large disparities, arguing that they are subserved by distinct neural mechanisms. Other studies have pointed to a ...

Developing previous work by R.C. Bose, R.M. Wilson, M. Greig and the author, we give a general construction for di erence families over nite elds. All the DFs constructed before were generated by a single initial base block so that they were uniform. Here we also consider DFs generated by two or more initial base blocks. These DFs give rise to pairwise balanced designs which of course are balan...

Global shape judgements were employed to examine the combination of stereopsis and shape-from-texture in the determination of three-dimensional shape. Adding textural variations to stereograms increased perceived depth. Thus, texture was not simply vetoed by the strong stereo cue. In experiments where the depth specified by texture was incongruent with that specified by stereo, the data were we...

"da Vinci stereopsis" is defined as depth seen in a monocular object occluded by a binocular one, and the visual system must solve its depth ambiguity [Nakayama, K., & Shimojo, S. (1990). da Vinci stereopsis: Depth and subjective occluding contours from unpaired image points. Vision Research, 30, 1811-1825]. Although fused images include various pictorial features, effects of pictorial depth cu...

Computational models of stereopsis employ a number of algorithms that constrain stereo matches to produce the smallest absolute disparity and to minimize the relative disparity between nearby features. In some natural scenes, such as large slanted textured surfaces, these two constraints lead to different matching solutions. The current study utilized a stimulus in which there was a large discr...

There are substantial differences in the relative size of tax bases across counties in Georgia. These differences mean that the ability or capacity to raise revenue differs across the State. For example, counties with large property tax bases per capita, i.e., those with large manufacturing facilities or power plants, have greater revenue raising potential than purely agricultural counties. Thi...
