  • Method and device for reducing a computational load in high efficiency video coding
    Patent number: 10085028
    Abstract: A method for reducing a computational load in high efficiency video coding includes generating a full rate distortion calculation list of selected intra coding modes where the intra coding modes including intra prediction modes and depth modeling modes. A rate distortion cost is determined, with a segment-wise depth coding mode being disabled, for each intra prediction mode in the full rate distortion calculation list and a smallest rate distortion cost intra prediction mode is selected. A rate distortion cost for a particular intra prediction mode is calculated with the segment-wise depth coding mode enabled. After comparison, one of the particular intra prediction mode and the smallest rate distortion cost intra prediction mode having the smallest rate distortion cost is applied to a prediction unit.
