Abstract
A method of determining the motion vector of a block of a video frame with respect to a reference video frame. The video frame and reference video frame comprising pixels, wherein each pixel has a pixel value. The method comprises first determining a plurality of sets of error norms, wherein each error norm within one of the sets is related to a different position of the block in the reference video frame, wherein the error norms are calculated by a norm of an error which is given by functions of the pixel values of the block of the video frame and the reference video frame, and wherein each set of the plurality of sets is related to a different function. Second, the motion vector is selected with the smallest error norm.
