  • Methods and apparatuses for video compression intra prediction mode determination
    Patent number: 8295349
    Abstract: A method and system for video compression prediction mode determination is disclosed. For one embodiment of the invention, the frequency domain characteristics (FDCs) of an image block are determined. The FDCs of the image block are compared to the FDCs of each of a number of prediction modes. The prediction mode having FDCs most similar to those of the image block is then determined and selected for encoding the block. For one embodiment of the invention the FDCs of the nine 4×4 prediction modes of the H.264 standard and the FDCs of a 4×4 image block are defined using a frequency domain transform. For one embodiment of the invention, one or more additional prediction modes are evaluated, and of these, the prediction mode resulting in RD optimization is selected for encoding the block.
