Abstract

Un aparato electrónico que ejecuta un método de decodificación de video, el cual comprende: recibir, de la señal de video, un fotograma de imagen que incluye un primer componente y un segundo componente; determinar un clasificador para el primer componente con base en un primer conjunto de una o más muestras del segundo componente asociado con una muestra respectiva del primer componente y un segundo conjunto de una o más muestras del primer componente asociado con la muestra respectiva del primer componente; determinar una desviación por muestra para la muestra respectiva del primer componente de acuerdo con el clasificador; y modificar un valor de la muestra respectiva del primer componente con base en la desviación por muestra determinada. En algunas modalidades, el primer componente es un componente de luminancia y el segundo componente es un componente de crominancia, y el clasificador se determina mediante una combinación de clasificador de desviación de banda y clasificador de desviación de borde.
