An effective algorithm of automatic video object segmentation based on temporal-spatial information

In video processing, Automatic video object segmentation is an important and difficult problem, we propose an effective algorithm of automatic video object segmentation based on temporal-spatial information. Firstly, we obtain video object mask based on temporal, position and motional information, then correct the contour of the obtained video object mask based on spatial information. We construct the background of video sequence and obtain the video object based on the corrected video object mask. The extraction and tracking of video object are completed by employing the information of background.
