METHOD AND APPARATUS FOR PALETTE BASED CODING MODE UNDER LOCAL DUAL TREE STRUCTURE

摘要

Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. For example, the processing circuitry decodes prediction information of a block from a coded video bitstream, determines whether to allow a palette based coding mode for the block based on a comparison of a size of the block with a threshold, and determines whether the block is under a local dual tree structure based on the prediction information. Further, the processing circuitry decodes the block based on the determination of whether to allow the palette based coding mode for the block and the determination of whether the block being under the local dual tree structure.
