Extracting high-quality dynamic foreground layers from a video sequence is a challenging problem due to the coupling of color, motion, and occlusion. Many approaches assume that the background scene is static or undergoes the planar perspective transformation. In this paper, we relax these restrictions and present a comprehensive system for accurately computing object motion, layer, and depth information...
Multi-channel display system is more suitable for collaboration applications than common desktop PC. In tradition, such multi-channel displays are used by a group of collocated users. In this paper, we propose one remote interaction system to allow a group of users to simultaneously access the multi-channel display on common PCs. Our system can achieve real time performance under mainstream network...
This paper presents a novel method for reconstructing high-quality video depth maps. A bundle optimization model is proposed to address the key issues, including image noise and occlusions, in stereo reconstruction. Our method not only uses the color constancy constraint, but also explicitly incorporates the geometric coherence constraint associating multiple frames in a video, thus can naturally...
