Abstract
Devices, systems and methods for adaptive loop filtering are described. In an exemplary aspect, a method for video processing includes performing, for a current video block of a video, a filtering process that uses filter coefficients and comprises two or more operations with at least one intermediate result, applying a clipping operation to the at least one intermediate result, and performing, based on the at least one intermediate result, a conversion between the current video block and a bitstream representation of the video, wherein the at least one intermediate result is based on a weighted sum of the filter coefficients and differences between a current sample of the current video block and neighboring samples of the current sample.
