Estimation of optical flow is an important topic to provide motion information for motion analysis. This paper addresses an effective confidence based optical flow algorithm. It considers the bidirectional symmetry of forward and backward flow to compute the confidence measure for each flow estimate. According to the confidence, the reliable flow estimates have greater contribution to local averages...
Extraction of moving objects is an important and fundamental research topic for many digital video applications. This paper addresses an efficient spatio-temporal segmentation scheme to extract moving objects from video sequences. The temporal segmentation yields a temporal mask that indicates moving regions and static regions for each frame. For localization of moving objects, a block-based motion...
