Abstract

La presente invención se refiere a un método de codificación de imágenes que incluye: derivar un candidato para un vector de movimiento de un bloque actual a partir de un vector de movimiento co-localizado (S1301); agregar el candidato a una lista (S1302); seleccionar el vector de movimiento del bloque actual de la lista (S1303); y codificar el bloque actual (91304), en donde la derivación (S1301) incluye: derivar el candidato por medio de un primer esquema de derivación en caso de determinar que cada una de una imagen de referencia actual y una imagen de referencia co-localizada es una imagen de referencia a largo plazo; y derivar el candidato por medio de un segundo esquema de derivación en caso de determinar que cada una de la imagen de referencia actual y la imagen de referencia co-localizada es una imagen de referencia a corto plazo.
