Claim 0:
1. A method for video coding, executable by a processor, the method comprising:
receiving video data;
determining a directionality of a sample block of the received video data by determining a sum of squared differences between the sample block and each of a plurality of target directional blocks and determining a directionality of a target directional block of the plurality of target directional blocks that has a minimum sum of squared differences as the directionality of the sample block and outputting a descriptor corresponding to the determined directionality of the sample block;
applying a geometric transformation in which filter coefficients of a cross-component filter or reconstructed samples in a filter support region are rotated by a first amount based on the directionality being a first direction and rotated by a second amount based on the directionality being a second direction different from the first direction; and
decoding the video data based on the applied geometric transformation.
