    摘要： Methods and apparatus for a classification-based loop filter are provided. An encoding method encodes an input picture by transforming and quantizing a residue of the input picture to obtain quantized transform coefficients. Then inverse quantizing and inverse transforming the quantized transform coefficients to obtain a reconstructed version of the residue. A reconstructed version of the input picture is obtained by combining at least one reference picture with the reconstructed version of the residue. Pixels in the reconstructed version of the input picture are classified within a respective one of a plurality of categories responsive to local geometric characteristics. Pixels are selected for filtering responsive to a corresponding classification of the pixels with respect to the plurality of categories.

    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 (400) 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.
