Abstract
Presents a processor-time optimal partitioned implementation of a stereo matching algorithm using zero crossing points as matching primitives. The authors provide O (nm /P ) time algorithm on √P ×√P processor mesh array, where n is the number of zero crossing points in the left image, m is the set of possible candidate points in the right image for a given zero crossing point, and 1⩽P ⩽ n . The sequential algorithm takes O (nm 2 ) time while the faster sequential algorithm shown in the paper runs in O (nm ) time
