Abstract
Se describen técnicas del modo de predicción de modelo lineal. Se determinan dos pares de valor de luma y valor de croma de acuerdo con N muestras de luma vecinas reconstruidas y N muestras de croma vecinas reconstruidas que corresponden a N muestras de luma vecinas reconstruidas y M muestras de luma vecinas reconstruidas que corresponden a M muestras de luma vecinas reconstruidas. El valor mínimo de N muestras de luma vecinas reconstruidas no es menor que el valor de luma de las N muestras de luma vecinas reconstruidas restantes del conjunto de muestras de luma vecinas reconstruidas. El valor máximo de las M muestras de luma vecinas reconstruidas no es mayor que el valor de luma de las muestras de luma vecinas reconstruidas restantes del conjunto de muestras de luma vecinas reconstruidas. M, N son números enteros positivos y son mayores que 1. Uno o más parámetros de modelo lineal se determinan con base en los dos pares de valor de luma y valor de croma, y un bloque predictivo se determina con base en el uno o más parámetros de modelo lineal.
