A stereo video segmentation algorithm combining disparity map and frame difference

In this paper, an algorithm to segment object from stereo video is presented. The algorithm combines the strong points of disparity map with frame difference. First, segment disparity maps to get the object segmentation template in different disparity lays. Then make frame difference extraction in the template regions to modify the object edge. After that the precise motion object has been gotten. The algorithm is low complexity and easy to realize. From the simulation results, we can conclude that the algorithm is efficient in segmentation when there is overlapping in different disparity motion objects or the background is moving.
