Abstract
Un método de decodificación de imágenes de conformidad con el presente documento se caracteriza por incluir: un paso para adquirir un índice de selección de transformación múltiple (MTS) e información residual de un flujo de bits; un paso para derivar coeficientes de transformación para el bloque actual sobre la base de la información residual; y un paso para generar muestras residuales del bloque actual sobre la base del índice MTS y los coeficientes de transformación, en donde el índice MTS indica un conjunto de núcleos de transformación que se aplicará al bloque actual entre los candidatos del conjunto de núcleos de transformación, al menos un intervalo entre bins de una cadena de bins del índice MTS se deriva sobre la base de la codificación de contexto, la codificación de contexto se realiza sobre la base de valores de aumento y disminución en un índice de contexto perteneciente al índice MTS, y un valor único de aumento y disminución en el índice de contexto se puede usar para la codificación de contexto del primer bin entre los bins de la cadena de bins.
