Stereo Correspondence Based On Multiresolution Analysis

Abstract

Disparity estimation from stereo imagery has gained substantial interest of research community from its commencement with the recent trend being the use of multiresolution methods. Existing multiresolution based methods generally rely on approximate band based matching neglecting other subbands that carry high-frequency information. Present research is an effort to find a multiresolution based stereo correspondence method that effectively uses the high and low-frequency subbands in multiple resolutions, bridges the gap between feature-based and area-based matching by incorporating the vast feature space of multiresolution and develops an optimum approach between global and local area-based methods in terms of accuracy, implementation and computational complexity. As a response to the lack of exploration of different multiresolution based stereo, a novel comprehensive comparison framework is proposed to evaluate different multiresolution based disparity estimation methods. Extensive qualitative and quantitative results with detailed analysis have been provided to support the claims of the work
