Abstract

Un sistema y método para codificar video en el que los artefactos de eliminación de bloques se reducen mediante el uso de filtrado modificado que se basa, al menos en parte en la intensidad de los píxeles asociados con una unidad de codificación, de manera que los niveles de filtrado aumentan a medida que aumenta la intensidad de los píxeles. En algunas modalidades, un valor de desplazamiento o indicador de un valor de desplazamiento para los parámetros asociados con los parámetros del filtro de eliminación de bloques puede asociarse con un nivel de filtrado que se basa al menos en parte en un valor de intensidad.
