Luma Mapping for Template Matching

원문 (중국어)

The current block may be predicted using a reference block and a difference between templates of the current bock and the reference block. The reference block may be selected from a plurality of candidate reference blocks. The selection may be based on a template matching cost that indicates the differences between the templates of the current block and the templates of a respective candidate reference block. An encoder or a decoder may transform samples from templates of the current block and of the candidate reference block into the same domain, for example, if the samples are in different domains before determining the template matching cost.
