    摘要: Methods and apparatus are provided for geometric-based intra prediction. An apparatus includes a video encoder for encoding picture data for at least a portion of a block in a picture by detecting a local geometric pattern in a surrounding area with respect to the portion, and performing at least one of interpolation and extrapolation with respect to an edge direction of the local geometric pattern to generate an intra prediction for the portion.

    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.
