Periodic Textures as Distinguished Regions for Wide-Baseline Stereo Correspondence

By Dmitry Chetverikov and Jirí Matas

Abstract

This paper addresses the problem of establishing correspondences for wide-baseline stereo, when two images are taken from significantly different viewpoints. Most of the existing approaches avoid using textures for matching as repetitive patterns tend to produce multiple peaks of correlation, which may lead to an ambiguity. We demonstrate that the presence of periodic textures can facilitate wide-baseline matching. The concept of a distinguished region is introduced and discussed. Dominant periodic patterns are used as distinguished regions whose affine-invariant descriptors, regularity feature vectors, are computed to identify regions in a wide-baseline stereo pair. Test results with various images are shown and discussed
