Combination of color and object outline based method in video segmentation

Video segmentation, storage and content-based retrieval become essential with the development of government affairs through network and web search. Segmentation and clustering of the video sequences are the first step should be taken to solve the problem. The conventional segmentation methods are based on histogram difference and pixel difference between the successive frame pairs, which usually can not show satisfying results. In this paper we make use of the mutual complementary features between the pixel gray distribution based method and the object outline based method throughout the frames to segment the video sequence hierarchically.
