Title
(EN) COMPLEXITY REDUCTION IN PARAMETER DERIVATION FOR INTRA PREDICTION
(FR) RÉDUCTION DE COMPLEXITÉ DANS UNE DÉRIVATION DE PARAMÈTRES POUR UNE PRÉDICTION INTRA
Abstract
(EN)
A method for video processing is provided. The method includes determining, for a conversion between a current video block of a video that is a chroma block and a coded representation of the video, parameters of a cross-component linear model using a parameter table whose entries are retrieved according to two chroma sample values and two luma sample values; and performing the conversion based on the determining.

L'invention concerne un procédé de traitement vidéo. Le procédé consiste à déterminer, pour une conversion entre un bloc vidéo courant d'une vidéo qui est un bloc de chrominance et une représentation codée de la vidéo, des paramètres d'un modèle linéaire à composantes croisées à l'aide d'une table de paramètres dont les entrées sont extraites selon deux valeurs d'échantillon de chrominance et deux valeurs d'échantillon de luminance ; et à réaliser la conversion sur la base de la détermination.
