Abstract
Un método de codificación de imágenes de acuerdo con el presente documento comprende los pasos de: derivar coeficientes de transformación para un bloque actual sobre la base de información relacionada con los residuos; y generar muestras residuales del bloque actual sobre la base de los coeficientes de transformación. La información relacionada con los residuos comprende información de índice de transformación no separable de baja frecuencia (LFNST), que muestra información relativa a la transformación no separable para los coeficientes de transformación de baja frecuencia del bloque actual, sobre la base de una bandera de intra predicción en base a matriz (MIP) que muestra si la MIP se aplica o no al bloque actual. Las muestras residuales se generan a partir de los coeficientes de transformación sobre la base de la información del índice LFNST.
