摘要：
A method of extracting a foreground object image from a video sequence includes producing a reference background image by separating a background image from a frame image of the video sequence; producing edge information of the frame image and the reference background image; producing an edge difference image using the edge information; and extracting the foreground object image using the edge difference image based on the edge information.
