Abstract
Se describe un método y aparato mejorados para desbloquear un filtro; en una modalidad de acuerdo con la presente invención, se omite determinar la existencia de coeficientes de transformada no cero para un límite únicamente de PU y por lo tanto, el desbloqueo del filtro para el límite únicamente de PU se elimina si la condición de la resistencia del límite igual a 1 no se cumple para evitar el desbloqueo innecesario; en otra modalidad de la presente invención, se determinan tres gradientes para dos líneas de pixeles y se toma la decisión de ENCENDIDO/APAGADO de filtro con base en los tres valores de gradientes de las dos líneas de pixeles; un aspecto de la invención se relaciona con la selección de resistencia del filtro entre filtros fuertes y débiles; de acuerdo con una modalidad, la selección de resistencia del filtro se basa en varios valores de gradiente de una línea de pixeles en el límite de bloque; otro aspecto de la invención se relaciona con el filtro más débil.
