PatchMatch-based Disparity Estimation in Stereo Videos with Spatio-temporal Slanted Windows

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a novel disparity estimation method using stereo videos. Previous studies estimate the disparity between two cameras by exploring the corresponding region with a spatial shape adaptation of the search window. In stereo videos, however, the moving objects are likely to exist; i.e., the corresponding region varies in the spatio-temporal domain. Therefore, previous studies are difficult to search the appropriate corresponding region. In order to address such problem, we propose a spatio-temporal slanted window to achieve accurate disparity estimation in stereo videos. Our spatio-temporal slanted window enables to change the search window adaptively in the spatio-temporal domain. To estimate the spatio-temporal slanted window, we exploit a PatchMatch algorithm. Using synthesized stereo videos, we demonstrate the effectiveness of our method.
