  • Patent number: 5978030
    Abstract: An apparatus for encoding a digital video signal to reduce a transmission rate of the digital video signal, which comprises a feature point based motion compensation circuit for selecting a set of feature points from the reconstructed reference frame to detect a set of motion vectors between a current frame and a original reference frame corresponding to the set of feature points by using a feature point based motion estimation, and for generating a second predicted frame based on the set of motion vectors and the reconstructed reference frame. The feature point based motion estimation employs a convergence process in which a displacement of each of the feature points are given to a motion vector thereof and the six triangles of each of the hexagon are affine-transformed independently using the displacements of their vertex feature points. If the displacements provide a better PSNR, the motion vector of the subject feature point is sequentially updated.

  • Patent number: 5598216
    Abstract: A video signal encoding apparatus determines quasi-feature points on the current frame based on selected feature points on the previous frame. A predicted current frame is obtained based on a number of triangle regions formed by the quasi-feature points. After determining a frame difference signal by subtracting the predicted current frame signal from the current frame signal, a plurality of processing regions are selected from the frame difference signal based on the magnitude of average pixel difference values corresponding to the triangle regions. Only the selected processing regions are then encoded for transmission to thereby reduce a transmission rate. A video signal decoding apparatus comprises corresponding circuits for decoding the selectively encoded video signal.

  • Patent number: 5581308
    Abstract: An inventive apparatus determines true motion vectors between a current and its previous frames for feature points selected from the previous frame wherein a selected feature point is surrounded by its neighboring four feature points to form a previous rhombus having a set of four triangles based on the selected feature point. A motion vector displacement generator gives a predetermined N number of displacements to an initial motion vector for its corresponding feature points to thereby produce a subset of N candidate motion vectors and a motion prediction block provides a current rhombus corresponding to the previous rhombus by the initial motion vectors, wherein the current rhombus has N sets of four triangles due to the N candidate motion vectors.
