Semiautomatic video object segmentation based background constructing

We propose an algorithm of semiautomatic video segmentation based background constructing. Firstly, we obtain the video object of the first frame by employing manual method, then, construct the background of the first frame, finally, the video object tracking is completed based on background updating and motion information of the video object. Our algorithm obtains a good tracking effect when the video object rapidly motions or is still. Experimental results are compared with the results of other algorithm, and demonstrate the performance of our algorithm.
