A fast parallel algorithm for stereovision

A new stereo algorithm based on local spatial filter operations and a fast coherence detection scheme is presented. The algorithm achieves performance similar to classical area-based approaches, but without the complicated hierarchical search structure typical for these approaches. The algorithm is fully parallel; disparity values and a corresponding verification count are calculated independently for each pixel. In addition, the network; structure is able to fuse the left and right input images of the scene within its fusion range into a single cyclopean view.
