Abstract
Specifically, a method decodes a picture. The picture is encoded and represented by blocks in a bitstream. For each block, a remap flag is obtained from the bit-stream. The block is either a remapped reconstructed block or a non-remapped reconstructed block. Either the non-mapped reconstructed block or an inverse remapped reconstructed block is output according to the remap flag. The remapped reconstructed block maximizes a similarity with the neighboring blocks, as compared to the similarity of the non-mapped reconstructed block and the neighboring blocks, by applying point operations to the remapped reconstructed block.
Claims16
A method for decoding a picture, wherein the picture is encoded and represented by blocks in a bitstream, comprising the steps of:
- obtaining, for each block, a remap flag from the bit-stream, Wherein the block is either a remapped reconstructed block or a non-remapped reconstructed block;
- and
- selecting, either the non-mapped reconstructed block, or an inverse remapped reconstructed block as a reconstructed block according to the rump flag, wherein the remapped reconstructed block maximized a similarity with neighboring blocks, as compared to the similarity of the non-mapped reconstructed block and the neighboring blocks, by applying point operations to the remapped it reconstructed block, wherein the steps are performed in a decoder.
The method of claim. 1, wherein the point operation minimizes a coding cost based on predictions from pixels in the neighboring blocks.
