Abstract

Un método de codificación de imágenes incluye: derivar un candidato para un predictor de vectores de movimiento a partir de un vector de movimiento (S1201); añadir el candidato a una lista (S1202); seleccionar un predictor de vectores de movimiento de la lista; codificar un bloque actual (S1203); y codificar un vector de movimiento actual (S1204) . En la derivación (S1201): el candidato se deriva de acuerdo con un primer esquema de derivación cuando se determina que cada una de una imagen de referencia actual y una imagen de referencia adyacentes es una imagen de referencia a largo plazo, y el candidato se deriva de acuerdo con un segundo esquema de derivación cuando se determina que cada una de una imagen de referencia actual y una imagen de referencia adyacentes es una imagen de referencia a corto plazo.
