Abstract
La presente invención se refiere al campo del procesamiento de imágenes; especialmente, la invención intenta mejorar la intra predicción (tal como la intra predicción de crominancia) utilizando un modelo lineal de componente cruzado (CCLM) y de manera más particular a la filtración espacial utilizada en modelo lineal de componente cruzado para intra predicción con diferentes formatos de crominancia; se proporciona un aparato, un codificador, un decodificador y métodos correspondientes para predicción de componente cruzado para una imagen, en la cual el conjunto de filtros de sub-muestreo aplicados durante la predicción depende de un formato de crominancia, que puede ser uno de múltiples formatos de crominancia soportados, a fin de mejorar la eficiencia de la codificación.
