Abstract: A mechanism for processing video data is disclosed. The mechanism determines to apply a bilateral filter to samples in a current block of a current picture. The bilateral filter includes filter weights that vary based on a distance between surrounding samples and a central sample and differences in intensities of the surrounding samples and the central sample. A conversion is performed between a visual media data and a bitstream based on the bilateral filter.

Abstract: A mechanism for processing video data is disclosed. A conversion is performed between a visual media data including a video unit and a bitstream. The conversion can be performed by a video encoder and/or a video decoder. The video unit is reconstructed, and a guided filter is applied to reconstructed samples in the video unit.

Abstract: A method of processing video data, comprising obtaining a non-adjacent reconstruction sample of a picture of a video, inputting the non-adjacent reconstruction sample of the picture as input for an adaptive loop filter (ALF), and performing a conversion between the video and a bitstream of the video based on the ALF.
