Method and apparatus for video processing

Abstract

Methods and apparatus for video coding using the ALF are disclosed. According to one method, a Temporal Adaptive Loop Filter (TALF) correction term is derived according to a TALF process for a target sample of the current block or a Neural Network-based in-Loop Filtering (NNLF) correction term is derived according to an NNLF process for the target sample of the current block. A first process correction term is derived according to a first process of in-loop filtering in parallel with the said TALF or NNLF process. A filtered target sample is generated by using the target sample, the first process correction term, and the TALF correction term / the NNLF correction term. In yet another embodiment, a flag is signalled at a CTU, CTB, CU, PU, or TU level associated with the current block, where the flag indicates a filtering mode for a Temporal Adaptive Loop Filter (TALF) process.
