【Abstract】 This paper presents an automatic generation algorithm for video objects. First, the current frame is global motion compensated after the global motion estimation, and the difference operation is made between the current frame and the previous frame. Then, motion region can be detected by using a fuzzy classifier and the binary models of video objects can be determined by combining motion region and edge information in the current frame. Finally, the video object can be generated according to its binary model. Experimental results show that the proposed algorithm is effective with strong robustness.更多还原
