    摘要: Methods and apparatus are provided for efficient adaptive filtering for video encoders and decoders. An apparatus includes a video encoder for encoding picture data for at least a portion of a picture using adaptive filtering. The video encoder includes an adaptive filter for performing the adaptive filtering. A final filter coefficient set used for the adaptive filtering is determined by iteratively estimating a plurality of filter coefficient sets and selecting a last estimated one of the plurality of filter coefficient sets as the final filter coefficient set when a last iteration corresponding to the last estimated one of the plurality of filter coefficient sets results in a quality improvement above a threshold value for the portion.

    摘要: Methods and apparatus are provided for DC intra prediction mode for video encoding and decoding. An apparatus includes a video encoder for encoding image data for at least a portion of an input picture by deriving a direct current prediction value from a pre-determined constant and using the derived direct current prediction value for a direct current intra prediction mode. The portion is encoded using the direct current intra prediction mode.

    摘要: Methods and apparatus are provided for signaling intra prediction for large blocks for video encoders and decoders. An apparatus includes a video encoder for encoding picture data for at least one large block in a picture by signaling intra prediction for the at least one large block. The intra prediction is signaled by selecting a basic coding unit size and assigning a single spatial intra partition type for the basic coding unit size. The single spatial intra partition type is selectable from among a plurality of spatial intra partition types. The at least one large block has a large block size greater than a block size of the basic coding unit. The intra prediction is hierarchical layer intra prediction and is performed for the at least one large block by at least one of splitting from the large block size to the basic coding unit size and merging from the basic coding unit size to the large block size.
