Abstract
A video coding method for cross-component sample adaptive offset (CCSAO) is provided. A video coder receives a current sample at a current pixel position of a current block being coded. The video coder selects one luma sample and two chroma samples as luma and chroma collocated samples of the pixel position. Only one or a subset of multiple candidate luma samples in a vicinity of the current pixel position is eligible to be the luma collocated sample of the current pixel position. The video coder selects a pixel category from multiple pixel categories based on the values of the selected luma and chroma collocated samples for the current pixel position. The video coder performs a lookup for an offset based on the selected pixel category. The video coder updates the current sample by applying the offset. The video coder encodes/decodes the current block based on the updated current sample.
