Video encoder with intra-prediction pre-processing and methods for use therewith

摘要

An intra-prediction module includes an intra-prediction preprocessor configured to process pixel data from blocks of picture data to determine edge strength data and edge angle range data corresponding to a plurality of pixels of the blocks, and further to generate intra-prediction candidate data based on the edge strength data and the edge angle range data. The intra-prediction candidate data indicates a first subset selected from a plurality of intra-prediction partitions and a second subset selected from a plurality of intra-prediction modes. A rate distortion optimization processor determines final intra-prediction data, based on the intra-prediction candidate data.

1. An intra-prediction module for use in a video encoder that encodes a video signal including picture data, the intra-prediction module comprising:
an intra-prediction preprocessor configured to process a plurality of pixels of blocks of the picture data to determine edge strength data and edge angle range data corresponding to the plurality of pixels of the blocks, and further to generate intra-prediction candidate data, wherein the intra-prediction candidate data indicates a first subset selected from a plurality of intra-prediction partitions and a second subset selected from a plurality of intra-prediction modes generated from the edge strength data and the edge angle range data; and a final intra-prediction processor, coupled to the intra-prediction preprocessor, that determines final intra-prediction data, based on rate distortion based costs of the intra-prediction candidate data.
