Abstract
Método para codificar un cuadro de video de entrada en un cuadro de video codificado. El método comprende los pasos siguientes: desensamblar el cuadro de video de entrada en una pluralidad de bloques de pixeles; y para cada bloque que es un bloque vigente, generar un bloque predicho correspondiente a partir de píxeles ya reconstruidos, generar un bloque residual mediante la sustraccion del bloque predicho con respecto al bloque vigente, y generar un bloque reconstruido a partir del bloque residual y del bloque predicho, generar el cuadro de video codificado a partir del bloque residual, crear una estructura local de pixeles reconstruidos en una region del bloque predicho y alinear el bloque predicho con la estructura local de manera de producir un bloque predicho alineado, en donde el bloque predicho alineado se utiliza en el paso de la generacion del bloque residual y de la generacion del bloque reconstruido correspondiente. Un método correspondiente para decodificar el cuadro de video codificado en un cuadro de video decodificado también utiliza un paso consistente en la creacion de una estructura local de píxeles reconstruidos en una region del bloque predicho y la alineacion del bloque predicho con la estructura local de manera de producir un bloque predicho alineado.
