    摘要: Methods and apparatus are provided for an adaptive directional filter for video restoration. An apparatus includes a video encoder for encoding at least a portion of a picture by categorizing pixels in the portion into respective ones of a plurality of groups, and selecting on a pixel basis filtering parameters for filtering the pixels responsive to the respective ones of the plurality of groups to which the pixels belong.

    摘要: Methods and apparatus are provided for intra coding a block having pixels assigned to groups. An apparatus includes a video encoder for encoding a block in a picture using intra prediction by dividing pixels within the block into at least a first group and a second group and encoding the pixels in the first group prior to encoding the pixels in the second group. A prediction for at least one of the pixels within the second group is obtained by evaluating the pixels within the first group and the second group.

    摘要: Methods and apparatus are provided for constrained transforms for video coding and decoding having transform selection. An apparatus includes a video encoder for encoding at least a block in a picture by selecting a particular transform from at least a first transform and a second transform that is different than the first transform, and applying the particular transform to a residue of the block. Transform coefficients for the second transform are selected responsive to a deblocking filter that is present in the video encoder.

    摘要: Methods and apparatus are provided for spatially varying residue coding. An apparatus includes a video encoder (300) for encoding picture data for at least a block in a picture by selecting a spatially varying encoding method for a residue corresponding to a difference between an original version of the block and at least one reference block. One or more transforms are used to transform a portion of the block and a remaining area of the block is encoded using an alternate encoding method with respect to the one or more transforms or is not encoded.
