H.264 Compressed Domain Moving Object Segmentation Used RSST Algorithm
应用递归最短生成树算法实现H.264压缩域运动对象分割方法

In this paper, we present a novel approach to segmenting moving objects from the H.264 compressed based on recursive shortest spanning tree(RSST). Firstly, the motion vector is obtained from the H.264 encoder and then a dense vector field is formed after the vector is unified and accumulated with a backward iterative projection process. Secondly, global motion compensation is used to eliminate the global motion. Thirdly, a modified RSST arithmetic is used to make the blocks clustered.Thus,with the proposed method we achieved moving object segmentation. Experimental results for several video sequences demonstrate the effectiveness of the proposed approach.
