Publication number: 20230353790Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry, in response to a first reconstructed image sample being located outside a virtual boundary, duplicates a reconstructed sample located inside and adjacent to the virtual boundary to generate the first reconstructed image sample. The circuitry generates a first coefficient value by applying a CCALF (cross component adaptive loop filtering) process to the first reconstructed image sample of a luma component. The circuitry generates a second coefficient value by applying an ALF (adaptive loop filtering) process to a second reconstructed image sample of a chroma component. The circuitry generates a third coefficient value by adding the first coefficient value to the second coefficient value, and encodes a third reconstructed image sample of the chroma component using the third coefficient value.Type: ApplicationFiled: November 2, 2022Publication date: November 2, 2023Inventors: Chu Tong WANG, Chong Soon LIM, Han Boon TEO, Hai Wei SUN, Jing Ya LI, Che-Wei KUO, Tadamasa TOMA, Takahiro NISHI, Kiyofumi ABE, Yusuke KATO
