Abstract
A method for image separating, said method being applied to an electronic apparatus to separate a foreground and a background of an image displayed on said apparatus, comprising the steps of scanning pixels in said image, applying arithmetic algorithm on said pixels and forming a plurality of segments on said image by defining pixels adjacent to each other and similar in color as one segment; examining foreground label and background label marked by an user; merging segments labeled by said foreground label into a foreground region and segments labeled by said background label into a background region, and applying arithmetic algorithm on an unlabeled segment to merge with an adjacent segment, foreground region or background region having the least difference in color; repeating said merging step until all segments are merged into a foreground region or a background region, thereby separating said image into a foreground region and a background region.
