In this paper, we propose a new automatic video object segmentation algorithm by integrating object registration and background constructing technology. We firstly obtain the initial video object based on motion information and frame difference information, then, obtain background information and subsequent frame object registration information. Finally, we keep track of video object by employing the object registration and background constructing technology. Object registration technology can keep right tracking when some parts of the object stop moving for many consecutive frames. When some parts of the object rapidly move, we obtain an accurate tracking by employing the background constructing technology. Experimental results were compared with other algorithm, and demonstrate the performance of our algorithm.
