Abstract

La presente invención proporciona un proceso de intrapredicción única que mejora la eficiencia de codificación de video. El H.264/AVC utiliza pixeles de referencia en un límite horizontal ubicado inmediatamente por encima de un bloque objetivo que se va a predecir, y pixeles de referencia en un límite vertical ubicado inmediatamente a la izquierda del bloque objetivo. En la presente invención, se recupera al menos alguna de una matriz de pixeles de límite horizontal y una matriz de pixeles de límite vertical. Luego, los pixeles recuperados se agregan a los otros pixeles de límite para extender la matriz de los mismos. La intrapredicción se lleva a cabo solamente con base en la matriz extendida de pixeles de límite.
