Abstract
Official abstract text for this publication.
The present invention relates to intra prediction which may be performed during encoding and/or decoding of an image signal. In particular, the present invention relates to intra prediction of a current block, during which filtering is applied to the prediction signal and/or to signal used for the prediction. The filtering is applied in accordance with a decision based on characteristics of image signal included in block(s) spatially adjacent to the current block.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for decoding, on a block-by-block basis, encoded image data partitioned into a plurality of blocks, said method comprising: deriving characteristics between image data of each of a plurality of previously decoded blocks spatially adjacent to a current block, the previously decoded blocks being used for intra prediction of the current block; deciding on the basis of the derived characteristics whether first filtering is to be applied or not t…
