Title
(EN) ADVANCED LINEAR MODEL PREDICTION FOR CHROMA CODING
(FR) PRÉDICTION DE MODÈLE LINÉAIRE PERFECTIONNÉE POUR CODAGE DE CHROMINANCE
Abstract
(EN)
An advanced linear model prediction method for chroma coding method is proposed. In the proposed method, more neighboring samples can be used to derive parameters. And more extensive LM modes are proposed.
(FR)
L'invention concerne un procédé de prédiction perfectionné de modèle linéaire pour codage de chrominance. Dans ledit procédé, plusieurs échantillons voisins peuvent être utilisés pour dériver des paramètres. Des modes de modèle linéaire (LM) plus importants sont également proposés.
