A video compression encoding process compresses or encodes dense motion vector fields to provide and improved compression ratio. In accordance with this method, a dense motion vector field is obtained for an object or a portion of an object between a pair of video image frames. The dense motion vector field may correspond, for example, to an object or other image portion of arbitrary configuration or size. The configuration of the dense motion vector field is extrapolated to a regular, preferably rectangular, configuration to facilitate encoding or compression. The dense motion vector field with its extrapolated regular configuration is encoded or compressed according to conventional encoding transformations such as, for example, discrete cosine transformation (DCT) or lattice wavelet compression.
