Abstract

Un método de decodificación de imágenes de acuerdo con el presente documento puede comprender: un paso para derivar un modo de inter predicción a partir de información codificada; un paso para construir listas de imágenes de referencia; un paso para derivar información de movimiento que incluya índices de imagen de referencia para diferencias de vectores de movimiento simétricos (SMVD) sobre la base de imágenes de referencia incluidas en las listas de imágenes de referencia; y un paso para generar muestras de predicción sobre la base de la información de movimiento. Los índices de imagen de referencia para SMVD pueden derivarse sobre la base de imágenes de referencia a corto plazo incluidas en las listas de imágenes de referencia.
