Abstract:
Segment-based methods become significant researches since they produce better result on the standard dataset [Scharstein and Szeliski 2002]. The kernel spirit is that all pixels in the same segment are regularized by a 3D geometric plane or a surface spline. This strategy better discriminates region discontinuities and achieves intra-object smoothing. However, few methods explicitly handle 2D-fragmented regions which are actually connected in 3D space. Such case often happens on the background occluded by several objects. To our knowledge, only object stereo [Bleyer et al. 2011] propose a 3D connectivity term in their optimization frame- work. Different from their method, our idea is to use proximity constraint based on color cues to evaluate the scene geometry. The proximity is widespread in real scenes and is recognized by human perception system – separate segments with similar colors usually come from the same object in real world. We propose a segment- based proximity formulation into the energy minimization frame- work. Figure 1 shows the proximity idea, the recovered segment connectivity, and the disparity reconstruction in case “cones” of the Middlebury dataset [Scharstein and Szeliski 2002].
