Spat io - Temporal Video Sequence Segment at ion

In the paper, an automatic spatio-temporal video sequence segmentation algorithm is proposed. To address this very daficult computer vision problem, several novel algorithms have been developed which use both spatial and temporal information. First, a novel temporal segmentation algorithm is developed based on our previous work in motion estimation. Second, an iterative split-and-merge spatial segmentation scheme is proposed with an initial segmentation being provided b y recursive conditioned dilation operation merging pixels into homogeneous regions, followed b y an iterative refinement algorithm to obtain the final spatial segmentation. Third, temporal and spatial segmentation are linked to form spatio-temporal segmentation with the shape of each object being simplified by a morphological close-opening operation to obtain the final segmentation. Performance evaluation shows that the developed algorithm can successfully segment moving object without any human intervention.
