Classification: CPC H | IPC H

Claim 0:
1. A decoding apparatus for image decoding, the decoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
receive image information through a bitstream;
generate reconstructed luma samples and reconstructed chroma samples based on the image information;
perform an adaptive loop filtering (ALF) process on the reconstructed chroma samples to generate filtered reconstructed chroma samples; and
perform a cross-component filtering process on the filtered reconstructed chroma samples to generate modified filtered reconstructed chroma samples,
wherein the image information includes an adaptation parameter set (APS) including ALF data including information on cross-component filtering,
wherein the ALF data includes information on a number of cross-component filters for the cross-component filtering and information on cross-component filter coefficients, and
wherein the modified filtered reconstructed chroma samples are generated based on the filtered reconstructed chroma samples and the cross-component filter coefficients.
