  • Method and apparatus for motion estimation in a video signal
    Patent number: 5838828
    Abstract: A method and apparatus for motion estimation in a video signal includes an edge detector for generating present and reference binary edge bit maps and a binary block matcher for receiving the present and reference binary edge bit maps from the edge detector and for generating a motion vector for each of a plurality of blocks in the binary edge bit maps. By using binary edge bit map data to generate motion vectors, computational requirements are reduced. If the apparatus is provided as an integrated circuit, the technique of the present invention reduces cost, power requirements and size of the integrated circuit.
