Abstract

Un aparato electrónico realiza un método de decodificación de datos de vídeo. El método incluye: recibir, desde la señal de vídeo, un marco de imagen que incluye un primer componente y un segundo componente; determinar un clasificador para el segundo componente a partir de un conjunto de una o más muestras del primer componente asociadas con una muestra respectiva del segundo componente; determinar si se debe modificar un valor de la muestra respectiva del segundo componente dentro de una región del marco de la imagen de acuerdo con el clasificador; en respuesta a la determinación de modificar el valor de la muestra respectiva del segundo componente dentro de la región de acuerdo con el clasificador, determinar un desplazamiento de muestra para la muestra respectiva del segundo componente de acuerdo con el clasificador; y modificar el valor de la muestra respectiva del segundo componente en función del desplazamiento de muestra determinado.
