Abstract

Un método de decodificación de imágenes realizado por medio de un dispositivo de decodificación de conformidad la presente descripción comprende los pasos de: derivar coeficientes de transformación de un bloque objetivo a partir de un flujo de bits; derivar un índice de transformación secundaria no separable (NSST) con respecto al bloque objetivo; realizar una transformación inversa con respecto a los coeficientes de transformación del bloque objetivo sobre la base del índice NSST y por lo tanto derivar muestras residuales del bloque objetivo; y generar una imagen reconstruida sobre la base de las muestras residuales.
