Abstract
A video object segmentation method applicable to a video system is presented. The method includes primarily segmenting objects existing in a frame of a video sequence manually or semi-manually. The objects within a video sequence including the primarily segmented object are automatically segmented. The method also determines whether any scene change is made between consecutive frames or any new object other than the primarily segmented object appears within the video sequence being automatically segmented, when repeatedly performing automatically segmenting the objects within the video sequence for consecutive frames. And, the method repeatedly performs primarily segmenting objects existing in a frame of a video sequence manually or semi-manually if it is determined that any scene change is made between consecutive frames or any new object other than the primarily segmented object appears within the video sequence being automatically segmented.
