Chroma deblock filters for intra picture block compensation
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. An apparatus for video decoding includes processing circuitry that decodes prediction information for a current block in a current picture. The prediction information indicates that a chroma coding block included in the current block is coded in an intra block copy mode and has a plurality of sub-blocks. The processing circuitry determines whether a first deblocking filter is to be applied to the plurality of sub-blocks of the chroma coding block. When the first deblocking filter is determined to be applied to the plurality of sub-blocks of the chroma coding block, the processing circuitry applies the first deblocking filter to samples adjacent to a boundary of a combined sub-block including a subset of the plurality of sub-blocks, and then reconstructs the current block based on the samples to which the first deblocking filter is applied.
