Trilateral-Filter-Based Depth Interpolation for Occlusion Handling in Stereo Vision

In this paper, we propose a trilateral-filter-based depth post processing to handle the occlusion points in order to enhance the quality of depth information and overcome the constraints in stereo vision. According to the experimental result, the depth quality is greatly enhanced especially in the occlusion regions and object boundaries. Proposed algorithm can provide high quality depth information from stereo image pair for the application, such as multi-view 3DTV. Keywords--Stereo vision, occlusion handling, depth interpolation.
