  • Method and apparatus for 3-D subband video coding
    Patent number: 7881374
    Abstract: A method of encoding and decoding a sequence of frames uses 3-D subband decomposition involving temporal filtering. Under certain conditions, for at least one pixel, the value of said pixel is approximated using one or more pixel values in the same frame.
    Type: Grant

    Date of Patent: February 1, 2011
    Assignee: Mitsubishi Denki Kabushiki Kaisha
    Inventors: Jordi Caball, Leszek Cieplinski
  • Intra-frame prediction for high-pass temporal-filtered frames in a wavelet video coding
    Publication number: 20060029136
    Abstract: A method of encoding a sequence of frames using 3-D decomposition including temporal filtering and using intra-frame prediction/interpolation, comprises (a) a first stage of intra-prediction/interpolation in which any neighbouring blocks may be used; (b) evaluating the intra-prediction/interpolation of step (a) for each block to identify blocks for intra-frame prediction; (c) a second stage of intra-prediction/interpolation wherein blocks identified in step (b) are not used for intra-prediction/interpolation of other blocks.
