Abstract

Un método de codificación de acuerdo a una modalidad que incluye un paso de ajuste de índice, un paso de predicción, y un paso de codificación. El paso de ajuste de índice ajusta un índice que representa información de una imagen de referencia y un factor de ponderación. El paso de predicción predice de modo que un valor de referencia del factor de ponderación cuando un valor de pixel cambia entre al menos una imagen de referencia y una imagen de destino para ser codificada es una referencia específica o menos se deriva como un valor previsto. El paso de codificación codifica un valor de diferencia entre el factor de ponderación y el valor previsto.
