    摘要: There are provided methods and apparatus for transform selection in video coding. An apparatus includes a video encoder for encoding at least a block in a picture by selecting a transform to apply to a residue of the block from a set of two or more available transforms. The transform is selected based on at least one of an inter prediction mode used to predict at least one reference for the block, one or more values corresponding to a motion vector, a value of a residue of one or more previously encoded blocks, a value of prediction data for the block, one or more transform selections of one or more neighboring reconstructed blocks, and a quantization step applied to transform coefficients for the residue of the block.

    摘要: There is disclosed a video encoder and corresponding method for encoding video data for an image block. The video encoder performs a mode decision by performing initial motion estimation on only a subset of possible block sizes to output motion information corresponding thereto, and determining, based upon the motion information corresponding to only the subset of possible of block sizes and upon other image-related analysis data, whether other block sizes are to be evaluated.

    摘要: There are provided a method and apparatus for reusing available motion information as a motion estimation predictor for video encoding. The apparatus includes an encoder for encoding an image block by determining a motion estimation predictor for the image block using motion information previously generated from an element other than the encoder, and using the motion estimation predictor in a motion estimation process to generate a motion vector for the image block. The motion estimation predictor is used in place of at least one predictor otherwise used in the motion estimation process. The at least one predictor is any of a search window predictor, a temporal predictor, and a block type predictor.
