Abstract
Template matching (TM) costs for a coding unit (CU) may be used to determine a bi-directional prediction with CU weights (BCW) weights to predict the CU. The TM cost may be determined based on templates of a block (e.g., a current block and/or a reference block). The TM cost may be determined based on one or more color component (e.g., collocated luma and chroma components) of the CU by calculating the TM cost as a weighted sum that may use the one or more color components.
Claims20
A method comprising:
- determining a template matching (TM) cost for a coding unit (CU) based on:
- a first TM cost that is based on a first color component of the CU;
- and
- a second TM cost that is based on a second color component of the CU;
- and
- based on the determined TM cost, determining a bidirectional prediction with coding unit weights (BCW) weight for predicting the CU.

A method, comprising:
- based on a first reference block associated with a coding unit (CU), determining a template matching (TM) cost for the CU based on two or more color components;
- and
- based on the determined TM cost, determining a bidirectional prediction with coding unit weights (BCW) weight for use in predicting the CU.
