Abstract
Un dispositivo de intradecodificación de la presente invención restaura un módulo residual cuantizado, información de intrapredicción, e información de tamaños de unidades de predicción del flujo de bits recibido; restaura un modo de intrapredicción de una unidad de predicción presente con base en la información de intrapredicción y la información de tamaño de la unidad de predicción presente; y filtra adaptativamente píxeles de referencia con base en el modo de intrapredicción mediante la generación de píxeles de referencia no utilizables de la unidad de predicción. Asimismo, la presente invención genera bloques de predicción utilizando y filtrando adaptativamente los píxeles de referencia que responden al modo de intrapredicción. Además, la presente invención genera imágenes restauradas utilizando los bloques de predicción y restaura bloques residuales. Por lo tanto, la presente invención mejora la compresibilidad de imágenes restaurando los bloques de predicción cercanos a la imagen original.
