An image processing method involves determining a global motion between a reference frame and a current frame in a frame sequence. A reference block is identified in the reference frame for a current block based on the global motion. A classification parameter is calculated based on the pixel values of the current block and the reference block. The parameter can be used for classifying the block as belonging to the background or foreground of the current frame. The parameter is preferably also utilized in frame rate-up conversion when extrapolating or interpolating new frames.
