Abstract:
1. A method of determining an optimized intra-predictor and optimized transform pair comprising: a. receiving one or more training videos; b. initializing each of a plurality of mode pairs, each mode pair of the mode pairs includes an intra-predictor and a transform, wherein the transforms of at least two of the plurality of mode pairs are different; c. encoding the one or more training videos using the plurality of mode pairs; d. accumulating statistics corresponding to the encoded one or more training videos; and e. modifying the intra-predictor and the transform within each mode pair according to the accumulated statistics, thereby forming a plurality of modified mode pairs, wherein the plurality of modified mode pairs are modified at least one additional time to generate a plurality of additional modified mode pairs, wherein an average performance of the plurality of additional modified mode pairs is measured and compared to the average performance from a previous iteration.
