Abstract
Un método de codificación de imágenes incluye codificar: (i) información de coeficientes; (ii) una primera bandera que indica si cuantificar o no uno o más bloques usando cuantificación; (iii) una segunda bandera que indica si incluir la pluralidad de matrices de cuantificación en un conjunto de parámetros de secuencia; y (iv) una tercera bandera que indica si incluir la pluralidad de matrices de cuantificación en un conjunto de parámetros de imagen; y cuantificar la pluralidad de coeficientes, donde cuando el uno o más bloques se cuantifican usando una pluralidad de matrices predeterminadas, en la codificación se codifican las siguientes: (i) la primera bandera que indica que el uno o más bloques se cuantifican usando la pluralidad de matrices de cuantificación; (ii) la segunda bandera que indica que no debe incluirse la pluralidad de matrices de cuantificación en el conjunto de parámetros de secuencia; y (iii) la tercera bandera que indica que no debe incluirse la pluralidad de matrices de cuantificación en el conjunto de parámetros de imagen.
