Abstract
A method, a non-transitory computer readable medium, and a computer system is provided for encoding or decoding video data. The method may include: receiving video data comprising a chroma component and a luma component; parsing, deriving or selecting a number of presets for the chroma component in one frame, and a number of presets for the luma component in the one frame; and decoding the video data. The method may further comprise: performing a separate Constrained Directional Enhancement Filter (CDEF) process of filtering luma and chroma components independent from each other based on the number of presets for the chroma component in one frame, and the number of presets for the luma component in the one frame.
