Abstract

Un método de codificación de imágenes incluye: derivar un candidato para un predictor de vector de movimiento a partir de un vector de movimiento vecino, agregar el candidato a una lista, seleccionar un predictor de vector de movimiento de la lista, codificar un bloque actual y codificar un vector de movimiento actual. En la derivación, 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 vecina es una imagen de referencia de larga duración 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 vecina es una imagen de referencia de corta duración.
