Abstract

Un método realizado por un dispositivo para filtrar un bloque actual adyacente a un bloque superior y un bloque izquierdo. El método incluye (1) filtrar una primera muestra situada en un área superior izquierda del bloque actual utilizando (i) al menos una muestra del bloque superior por encima del área superior izquierda, (ii) al menos una muestra del bloque izquierdo, y (iii) al menos un valor de muestra no filtrada para la primera muestra; (2) filtrar una segunda muestra situada en un área superior derecha del bloque actual utilizando (i) al menos una muestra del bloque superior y (ii) al menos un valor de muestra no filtrada para la segunda muestra; y (3) filtrar una tercera muestra situada en un área inferior izquierda del bloque actual utilizando (i) al menos una muestra del bloque izquierdo y (li) al menos un valor de muestra no filtrada para la tercera muestra.
