Abstract: This paper demonstrates how to effectively exploit occlusion and reappearance information of feature points in structure and motion recovery from video. Due to temporary occlusion with foreground objects, feature tracks discontinue. If these features reappear after their occlusion, they are connected to the correct previously discontinued trajectory during sequential camera and scene estimation. The combination of optical flow for features in consecutive frames and SIFT matching for the wide baseline feature connection provides accurate and stable feature tracking. The knowledge of occluded parts of a connected feature track is used to feed a segmentation algorithm which crops the foreground image regions automatically. The resulting segmentation provides an important step in scene understanding which eases integration of virtual objects into video significantly. The presented approach enables the automatic occlusion of integrated virtual objects with foreground regions of the video. Demonstrations show very realistic results in augmented reality. (More)
