Study of occlusion problem in stereo matching

The occlusion problem in the field of stereo matching is analyzed systematically by finding out reasons why the problem arises. Combining the literature published in recent years, the ideas and algorithms to solve the occlusion problem are summarized and classified. The contribution of this paper is to help other researchers to gain an overall understanding of occlusion, which enables them to choose suitable post-processing algorithms and improves the performance of stereo matching algorithm.
