基于稀疏的视频跟踪算法，能够较好的解决遮挡，噪声等干扰-Sparse-based video tracking algorithm can solve the occlusion, noise and interference

有关于目标跟踪算法中遮挡问题的研究，有对目标跟踪有研究的同学可以-There is research on the occlusion of the target tracking algorithm, target tracking studies, students can look

Diffuse objects generally tell us little about the surround- ing lighting, since the radiance they reflect blurs together incident lighting many directions. In this paper we discuss how occlusion geometry can help invert diffuse reflectance t
