Abstract

Se describe un método de decodificación de video inter-capa que incluye decodificar una imagen de primera capa, determinar una ubicación de referencia de la imagen de primera capa que corresponde a una ubicación de un bloque actual de segunda capa, determinar valores de muestra adyacentes al utilizar valores de muestra de un límite de la imagen de primera capa cuando ubicaciones de muestra adyacentes de la ubicación de referencia están fuera del límite de la imagen de primera capa, y determinar un parámetro de compensación de iluminación del bloque actual de segunda capa con base en los valores de muestra adyacentes.
