Abstract

Un método de decodificación de imágenes de acuerdo con el presente documento comprende los pasos de: recibir un elemento de sintaxis de intra-MIP para un primer bloque objetivo; derivar el valor del elemento de sintaxis de intra-MIP; establecer un indicador de MIP variable para el área específica preestablecida, que es la misma que el área del primer bloque objetivo, sobre la base del valor del elemento de sintaxis de intra-MIP; derivar un modo de intra predicción del segundo bloque objetivo sobre la base del indicador de MIP variable; y derivar una muestra de predicción del segundo bloque objetivo sobre la base del modo de intra predicción del segundo bloque objetivo.
