| Abstract(in English) | In stereovision algorisms, occlusion is a serious problem for matching corresponding pixels. This paper proposes a novel segment-based stereo matching algorithm that solves the occlusion problem. The algorithm first extracts occluded region from divided segments, then performs correspondence matching between left and right segments compensating t evaluated estimates for the occluded region. Furthermore, a surface gradient of segments are also estimated by merging adjacent segment depth infomation and finally dense depth map is estimated. The proposed method is implemented and evaluated. The experimental results show that the depth of occluded regions is estimated correctly. |
