  Abstract

This paper proposes a region-based segmentation algorithm for extracting a video object by using the cost of potential of frame-difference energies. In the first step of a region-based segmentation using spatial intensity, each frame is segmented into a partition of homogeneous regions finely so that each region does not contain the contour of a video object. The fine partition is used as an initial partition for the second step of spatio-temporal segmentation. In spatio-temporal segmentation, the homogeneity cost for each pair of adjacent regions is computed which reflects the potential between the frame-difference energy on the common contour and the frame-difference energy of the lower potential region of the two. The pair of adjacent regions whose cost is minimal then is searched. The two regions of minimum cost are merged, which result in updating the partition. The merging is recursively performed until only the contours remain which have frame difference energies of high potential. In the final step of post-processing, the video object is extracted removing the contours inside the object.
