ABSTRACT:
A method of selecting motion vectors in a motion estimation system involves calculating values of an evaluation function. Each evaluation function value corresponds to a block of pixels of a reference window with respect to a current block of pixels and the relative position of the blocks is described by a motion vector. The method also involves determining the smallest value of the evaluation function and comparing the norms of the vectors associated with the smallest value. The vector having the smallest norm is selected from the associated motion vectors.
