摘要

Decoders can use prediction based on weighted distortion to determine information used to make decisions regarding motion vectors, reference pixels, and coding modes, similar to a corresponding encoder operation. Samples in and around a current block and samples of reference pictures are weighted and a distortion metric generated to determine the decisions. Embodiments are described for prediction modes such as Cross-component linear model (CCLM), Local Illumination Compensation (LIC), and Frame Rate Up-Conversion (FRUC). Various embodiments describe derivation of weighting factors used in the decision making, comprising inference by a decoder, basing weighting factors on a quantization parameter, local activity of a block, and samples of temporally close reference pictures.
