Optimal disparity estimation in natural stereo images.

A great challenge of systems neuroscience is to understand the computations that underlie perceptual constancies, the ability to represent behaviorally relevant stimulus properties as constant even when irrelevant stimulus properties vary. As signals proceed through the visual system, neural states become more selective for properties of the environment, and more invariant to irrelevant feature...

Optimal defocus estimation in individual natural images.

Defocus blur is nearly always present in natural images: Objects at only one distance can be perfectly focused. Images of objects at other distances are blurred by an amount depending on pupil diameter and lens properties. Despite the fact that defocus is of great behavioral, perceptual, and biological importance, it is unknown how biological systems estimate defocus. Given a set of natural sce...

Disparity-Space Images and Large Occlusion Stereo

A new method for solving the stereo matching problem in the presence of large occlusion is presented. A data structure | the disparity space image | is deened in which we explicitly model the eeects of occlusion regions on the stereo solution. We develop a dynamic programming algorithm that nds matches and occlusions simultaneously. We show that while some cost must be assigned to unmatched pix...

Optimizing Disparity Candidates Space in Dense Stereo Matching

In this paper, a new approach for optimizing disparity candidates space is proposed for the solution of dense stereo matching problem. The main objectives of this approachare the reduction of average number of disparity candidates per pixel with low computational cost and high assurance of retaining the correct answer. These can be realized due to the effective use of multiple radial windows, i...

Optimization of Stereo Disparity Estimation Using theInstantaneous

The use of phase diierences from Gabor lter responses is a well established technique for the computation of stereo disparity. It achieves the subpixel estimation of disparity without applying a correspondence search. However, the success of the phase approach has not been thoroughly analyzed. Here, we study the eeects of varying lter frequency on the disparity estimation and we compare it to t...
