Abstract
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding, In some examples, an apparatus for video decoding includes processing circuitry, For example, the processing circuitry generates first reconstructed samples of a block, and applies a filter to multiple color components of the first reconstructed samples of the block to determine offsets to he applied to one or more color components. Then, the processing circuitry generates second reconstructed samples of the block based on the offsets for the one or more color components and the first reconstructed samples of the block.
Claims20
A method for video encoding, comprising:
- acquiring first samples of a block of an image in a video bitstream;
- generating an enabling flag that indicates two or more color components to which a filter is to be applied and indicates one or more color components to which offsets are to be applied;
- and
- encoding the first samples and transmitting, to a video decoding apparatus, a coded video bitstream including the encoded first samples and the generated enabling flag.
The method of claim wherein the enabling flag causes the video decoding apparatus to
- apply the filter to three color components of the first samples of the block to determine an offset to be applied to each of the three color components.
The method of claim wherein the enabling flag causes the video decoding apparatus to perform at least one of:
- applying the titter with different filtering shapes to different color components in the two or more color components of the first samples;
- and
- applying, the filter with different filtering sizes to different color components in the two or more color components of the first samples.
An apparatus for video processing, comprising:
- processing circuitry configured to:
- acquire first samples of a block of an image in a video bitstream;
- generate an enabling flag that indicates two or more color components to which a filter is to be applied and indicates one or more color components to which offsets are to be applied;
- and
- encode the first samples and transmitting, to a video decoding apparatus, a coded video bitstream including the encoded first samples and the generated enabling flag.
