METHOD AND APPARATUS FOR CROSS COMPONENT FILTERING

Abstract:

Methods and apparatuses for video processing include: filtering a luma sample using a first filter in a video coding process, the first filter being represented as a cross shape; filtering a chroma sample associated with the luma sample using a second filter in the video coding process; determining, based on the filtered luma sample, a residual correction value corresponding to the chroma sample; and determining a corrected chroma sample based on the residual correction value and the filtered chroma sample.
