Abstract
An innovative method and apparatus for decoding an encoded image such as a video. In one embodiment a method for decoding an encoded block of an image, e.g.,a video frame, having an error in its motion vector is disclosed. Sub-blocks are extracted from neighboring blocks to the encoded block. A motion vector is generated for each sub-portion and the generated motion vectors are used, for example, averaged, to estimate a motion vector for the encoded portion.
