Abstract
Aspects of the disclosure provide a method and an apparatus for video decoding. The apparatus includes processing circuitry that decodes prediction information indicating bi-prediction with coding unit (CU)-level weights (BCW) for a current block in a current picture. The processing circuitry performs template matching (TM) on BCW candidate weights by determining a respective TM cost corresponding to each BCW candidate weight. Each TM cost is determined based on a portion or all of a current template of the current block and a respective bi-predictor template. The bi-predictor template is based on the respective BCW candidate weight, a portion or all of a first reference template in a first reference picture, and a portion or all of a second reference template in a second reference picture. The processing circuitry reorders the BCW candidate weights based on the respectively determined TM costs.
