Predicting chroma from luma in av1

WebSep 24, 2024 · Specifically, the performance of chroma intra prediction can be improved by refined down-sampling or by incorporating location information. Experimental results show that the two proposed methods obtain 0.31 2.02 respectively, under All-Intra configuration, when implemented in Versatile Video Coding (H.266/VVC) test model. WebChroma from luma (CfL) prediction is a new and promising chroma-only intra predictor that models chroma pixels as a linear function of the coincident reconstructed luma pixels. In this paper, we present the CfL predictor adopted in Alliance Video 1 (AV1), a royalty-free video codec developed by the Alliance for Open Media (AOM).
