ABSTRACT:
The present invention discloses a method for extracting an object region in a motion picture, which can extract the object region of a current frame using different methods based on a degree of motion of the object. Especially, when the object has many motions, an object region of a previous frame is modified by comparing a CDI (Change Detected Image) generated based on a difference between the previous frame and the current frame with the previous frame. As a result, the present invention can be applied to image communication requiring real-time processing, and also applied to techniques requiring precise background change by dividing the object region in pixel units.
