Improving chroma intra prediction for hevc
WitrynaThis mode exploits inter-channel correlation using reconstructed luma to predict chroma linearly with parameters derived from neighboring reconstructed luma and chroma pixels at both encoder and decoder to avoid overhead signaling. In this paper, we analyze the LM mode and prove that the LM parameters for predicting original chroma and ... WitrynaIn intra-prediction mode, HEVC uses a quadtree structure with only square PUs, while in inter prediction mode ... The maximum transform size is 128 × 128 pixels, which …
