Abstract

Un método para llevar a cabo intrapredicción para codificación o decodificación utiliza múltiples capas de muestras de referencia. Las capas se forman en arreglos de referencia que son utilizadas por una función, tal como una combinación ponderada, para formar una predicción final. Los pesos pueden ser variables, elegidos entre un número de conjuntos de pesos. La predicción se utiliza para codificar o decodificar un bloque de datos de vídeo. Los pesos se pueden determinar de un número de formas, y para un modo de predicción dado, se pueden utilizar los mismos pesos, o diferentes pesos para todos los pixeles en un bloque objetivo. Si los pesos son variados, pueden depender de la distancia del pixel objetivo desde los arreglos de referencia. Se puede enviar un índice indicando qué conjunto de pesos se debe utilizar.
