Abstract
Se proporciona un método para la codificación de video. El método incluye: derivar un vector de movimiento (MV) inicial de una unidad de codificación (CU) actual; derivar una pluralidad de candidatos de vector de movimiento (MV) para el refinamiento del vector de movimiento en el decodificador (DMVR); determinar los valores de costo para el MV inicial y cada uno de los candidatos de MV; obtener valores de costo actualizados al ajustar por lo menos uno de los valores de costo para favorecer al MV inicial; y derivar un vector de movimiento (MV) refinado con base en los valores de costo actualizados del MV inicial y los candidatos de MV.
