Method and Apparatus for Adaptive Loop Filter with Chroma Classifier for Video Coding

原文（中国語）

Method and apparatus for video coding using chroma classification for chroma ALF. According to this method, reconstructed pixels are received, where the reconstructed pixels comprise a current colour block and the current colour block comprises a luma block and one or more chroma blocks. A filtered luma output is derived from one luma ALF selected from a set of luma ALFs according to luma block classification derived for each luma ALF classification block of the luma block. A filtered chroma output is derived from one chroma ALF selected from a set of chroma ALFs according to chroma block classification derived for each chroma ALF classification block of each of said one or more chroma blocks. Filtered-reconstructed pixels are provided, where the filtered-reconstructed pixels comprise the filtered luma output and the filtered chroma output.
