Abstract
La presente descripción relaciona un filtro, un codificador y un decodificador que usa el filtro, un método de filtrado y un programa correspondiente, así como la codificación y decodificación usando el método de filtrado o el filtro. El filtrado incluye la obtención de un bloque reconstruido extendido extendiendo el bloque reconstruido actual para incluir al menos muestras de relleno del bloque reconstruido actual. Después del relleno, un píxel actual del bloque reconstruido extendido y sus píxeles vecinos se cargan en un búfer lineal y se transforman con una transformación 1D. El filtrado se realiza en el dominio de la frecuencia utilizando una tabla de consulta y los píxeles filtrados se transforman de nuevo.
