Subsampled Sum-Modified-Laplacian for Adaptive Loop Filter in Versatile Video Coding

This paper proposes a Subsampled Sum-Modified-Laplacian (SSML) operator for the block classification of the Adaptive Loop Filter (ALF) in Versatile Video Coding (VVC). The VVC Test Model (VTM)-2.0 includes Geometry transformation-based ALF (GALF) with 4 × 4 block classification, a single...
