Loop filtering method and device, computer system and mobile equipment

Abstract

The invention discloses a loop filtering method and device, a computer system and mobile equipment. The method comprises the following steps: determining the number of types of filters adopted by loopfiltering; and determining whether to write the filter label corresponding to the pixel type into the code stream according to the number of the types of the filters. According to the technical scheme, the compression efficiency can be improved.

Background technique [0004] Loop filtering is a key part of the video codec framework. It is mainly used to reduce compression distortion such as blocking effect and ringing effect generated in the encoding process. At present, there are mainly three kinds of loop filtering techniques, namely deblocking filtering, adaptive sample value compensation filtering and adaptive loop filtering (Adaptive loop filter, ...
