US 2025/0030899 A1 · NONLOCAL LOOP FILTER FOR VIDEO CODING

Abstract

A method for video encoding, a method for video decoding, apparatuses and non-transitory computer-readable storage media thereof are provided. In the method for video decoding, the decoder may obtain one or more filtering parameters, wherein the one or more filtering parameters are from a filtering parameter set comprising a number of similar blocks, a search range, and a window size; obtain, based on the one or more filtering parameters, one or more similar pixels for a first pixel that has been filtered in a picture and the first pixel; and obtain an original pixel associated with the first pixel based on the one or more similar pixels.

A method for video decoding, comprising:

obtaining, by a decoder, one or more filtering parameters, wherein the one or more filtering parameters are from a filtering parameter set comprising a number of similar blocks, a search range, and a window size;
obtaining, by the decoder and based on the one or more filtering parameters, one or more similar pixels for a first pixel that has been filtered in a picture and the first pixel;
and
obtaining, by the decoder, an original pixel associated with the first pixel based on the one or more similar pixels.
