1. A method for video processing, the method comprising performing by one or more processors and/or circuits: determining a corresponding luma component and a corresponding chroma component of a sample of a composite video baseband signal for each of a plurality of filtering modes; determining a similarity level of said sample corresponding to each of said plurality of filtering modes; generating a corresponding coefficient for each of said plurality of filtering modes based on said determined similarity levels; and generating a luma component and a chroma component of said sample of said composite video baseband signal based on said generated corresponding coefficients and said determined corresponding luma components and said determined corresponding chroma components for each of said plurality of filtering modes.
