Abstract

Un método de codificación de imágenes incluye: generar un bloque predicho (S6001); calcular un bloque residual (S6002); calcular coeficientes cuantificados al realizar una transformación y una cuantificación en el bloque residual (S6003); calcular un bloque residual codificado al realizar una cuantificación inversa y una transformación inversa en los coeficientes cuantificados (S6004); generar un bloque codificado provisional (S6005); determinar si se requiere o no un proceso de compensación, para generar una primera información de indicador que señala un resultado de la determinación (SE 006); ejecutar el proceso de compensación en el bloque codificado provisional cuando se determina que se requiere el proceso de compensación (S6012); y realizar una codificación de longitud variable en los coeficientes cuantificados y la primera información de indicador (S6011).
