Abstract An object tracking method for semiautomatic video object segmentation is proposed in this paper. An objective function is constructed with mean square color error of blocks and edge strength of pixels. Then a multilevel ordering method with permissive error is used to accomplish the programming of this objective function so as to realize motion estimation and compensation of contour pixels. Thus the pixels in the current frame, which correspond to the contour pixels in the reference frame, are found out. As the contour pixels in the current frame, these pixels are connected to form a close curve by an objective of maximal edge strength. Thus the segmentation mask of the current frame is generated. The experimental results of this method on several test sequences are satisfactory.
