An apparatus, a method and a computer program for video coding and decoding

Abstract

A method comprising: obtaining a first set of reconstructed samples of a first color channel of an image; obtaining a second set of reconstructed samples of a second color channel of the image; providing the first set of reconstructed samples and the second set of reconstructed samples as input to a cross-component model filter derivation process; applying cross-component filter coefficients obtained from the cross-component filter derivation process in a cross-component filter provided with the first set of reconstructed samples and the second set of reconstructed samples as inputs to obtain an additional input for reconstructing the second set of samples; applying a first adaptive in-loop filter for the first set of reconstructed samples; and applying a second adaptive in-loop filter during a filtering stage of the second set of reconstructed samples.
