Occlusion detectable stereo-systematic comparison of detection algorithms

In stereo algorithms with more than two cameras, the improvement of accuracy in correspondence search is often reported. On the other hand, another important aspect of the polynocular stereo is the ability of occlusion detection. The camera matrix stereo SEA, which we have developed, offers a simple but effective framework to detect the presence of occlusion and to obtain reliable correspondence. SEA can produce a dense and accurate depth map with sharp object profiles. In this paper, we made some systematic comparison of several algorithms for occlusion detection in SEA. The results are quite interesting and reasonable. They are useful to design an actual polynocular stereo system.
