Method and apparatus of unified classification in in-loop filtering in video coding

Abstract

A method and apparatus for in-loop filtering of reconstructed video are disclosed. According to the method, input data for a current block is received, wherein the input data comprises reconstructed samples of the current block. At least two in-loop filters are applied to the current block, wherein said at least two in-loop filters belong to an in-loop filter group comprising BIF (Bilateral Filter) and ALF (Adaptive Loop Filter), and wherein classification processes of said at least two in-loop filters share an input source, one or more classification rules, one or more processing units, or a combination thereof. Filtered output generated by said applying said at least two in-loop filters to the current block is provided.

Dependencies are inferred from the claim text.
