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...
متن کاملNeural disparity map estimation from stereo image
In this paper, we propose a new approach of dense disparity map computing based on the neural network from pair of stereo images. Our approach divides the disparity map computing into two main steps. The first one deals with computing the initial disparity map using a neuronal method Back-Propagation (BP). The BP network, using differential features as input training data can learn the function...
متن کاملMotion Estimation from Disparity Images
A new method for 3D rigid motion estimation from stereo is proposed in this paper. The appealing feature of this method is that it directly uses the disparity images obtained from stereo matching. We assume that the stereo rig has parallel cameras and show, in that case, the geometric and topological properties of the disparity images. Then we introduce a rigid transformation (called d-motion) ...
متن کاملDisparity from Stereo-segment Silhouettes of Weakly-textured Images
In stereo vision, 3D information is reconstructed from two images of the same scene taken from different viewpoints. Different approaches to stereo disparity estimation have been extensively compared in several studies [1, 3]. Most stereo algorithms perform well in textured image areas, but often fail when there is only weak texture, due to the correspondence problem. Here local matching fails,...
متن کاملDisparity-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...
