METHOD AND APPARATUS FOR ADAPTIVE LOOP FILTER WITH NON-SAMPLE TAPS FOR VIDEO CODING

WIPO Patent Application WO/2024/055842

A1

A method and apparatus for video coding using ALF with non-sample-value filter taps. According to the method, reconstructed pixels are received, wherein the reconstructed pixels comprise a current block. A current filtered output from an ALF for a current sample in the current block is derived, wherein the ALF comprises at least one non-sample-value term derived using target information unrelated to sample values of the current block and the target information is derived at an encoder side, or derived or received at a decoder side. Filtered-reconstructed pixels are provided, wherein the filtered-reconstructed pixels comprise the current filtered output.
