Abstract

Se proporciona un codificador de imágenes que incluye un circuito y una memoria acoplada al circuito. El circuito, en operación, lleva a cabo una operación de suavizado de límite a lo largo de un límite entre una primera división que tiene una forma no rectangular (por ejemplo, una forma triangular) y una segunda división que se dividen a partir de un bloque de imagen. La operación de suavizado de límite incluye: primera predicción de primeros valores de un conjunto de pixeles de la primera división a lo largo del límite, usando información de la primera división; segunda predicción de segundos valores del conjunto de pixeles de la primera división a lo largo del límite, usando información de la segunda división; ponderar los primeros valores y los segundos valores; y codificar la primera división usando los primeros valores ponderados y los segundos valores ponderados.
