Abstract: A mechanism for processing video data is disclosed. The mechanism determines to apply a bilateral filter and a cross component sample adaptive offset (CCSAO) 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 and the CCSAO filter.

Abstract: A mechanism for processing video data is disclosed. One or more extended taps are determined for use in an adaptive loop filter (ALF). A conversion is performed between a visual media data and a bitstream based on the extended tap in the ALF. The extended tap may receive input data from different pictures than the current picture and/or from outside the spatial domain.

Abstract: A mechanism for processing video data is disclosed. A conversion is performed between a visual media data including a plurality of video units and a bitstream. A guided filter is applied to samples in the video units. The guided filter is applied at a post decoding stage, such as in an in-loop filtering process.

Abstract: A method of processing media data. The method includes filtering a sample of a video unit using one or more virtual filters of a fusion mode to produce a filtering result; and performing a conversion between a video including the video unit and a bitstream of the video based on the sample as filtered. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.

Abstract: A mechanism for processing video data is disclosed. The mechanism determines to classify picture data into groups based on statistical information related to the picture data and apply a bilateral filter to filter samples in each of the groups. A conversion is performed between a visual media data and a bitstream based on the bilateral filter.

Abstract: A method of processing media data. The method includes applying a fusion mode to an in-loop filtering method, a pre-processing method, or a post-processing method to filter a video unit in video coding; and performing a conversion between a video including the video unit and a bitstream of the video based on the fusion mode used. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.

Abstract: A method for processing video data includes using one or more extended taps in an ALF or a CCALF and performing a conversion between a visual media data and a bitstream based on the extended taps used in the ALF. A syntax element structure in the bitstream contains one or more filters with at least one extended tap. A first syntax element is in the bitstream to indicate whether a filter with at least one extended tap is enabled.

Abstract: A mechanism for processing video data is disclosed. A filter is applied to a video unit. The filter employs an extended tap for a first sample in the video unit and a spatial tap for a second sample in the video unit. A conversion is performed between a visual media data and a bitstream based on the video unit.

Abstract: A method of processing media data. The method includes fusing a plurality of intermediate filtering results of an adaptive loop filter (ALF) processing unit with a fusion mode to generate a final filtering result; and performing a conversion between a video including the ALF processing unit and a bitstream of the video based on the final filtering result. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.
