Abstract
Se proporciona un método que determina una intensidad límite en cada borde de 4 muestras que yace en la rejilla de 8x8 muestras, que determina si se realiza o no la filtración de desbloqueo en el borde de 4 muestras si la intensidad límite no es igual a cero, que selecciona un filtro de desbloqueo si la filtración de desbloqueo se realiza en el borde de 4 muestras, y que filtra el borde de 4 muestras utilizando el filtro seleccionado. De acuerdo con esto, la complejidad computacional requerida para determinar la intensidad límite de acuerdo a la presente invención se reduce al 50% o más en comparación con la HEVC en desarrollo. También, la capacidad de memoria y ancho de banda requeridos para determinar la intensidad límite se reducen al 50% o más sin el deterioro de la calidad de imagen.
