ABSTRACT:
A method of automatically dividing the domain of a motion picture is disclosed including the steps of: quantizing at least two sequential picture frames, and simplifying the shapes of the quantized picture frames; obtaining time space slope information from the quantized and simplified picture frames; detecting divides of the picture from the time space gradient information, and obtaining the boundaries between the divides, so as to divide the picture into multiple regions; combining neighboring smaller regions using graph theory, to thereby reduce the number of the divided regions; and dividing the regions into a motionless background object and moving objects, using motion information of the combined regions.
