Abstract
Se proporcionan sistemas y técnicas para el procesamiento de datos de video. Por ejemplo, los sistemas y técnicas pueden incluir obtener una imagen actual de datos de video y obtener imágenes de referencia para la imagen actual a partir de los datos de video. Se puede determinar un candidato de modo de fusión para la imagen actual. El primer y segundo vectores de movimiento se pueden identificar para el candidato de modo de fusión. Se puede seleccionar una estrategia de búsqueda de vectores de movimiento para el candidato de modo de fusión a partir de una pluralidad de estrategias de búsqueda de vectores de movimiento. La estrategia de búsqueda de vectores de movimiento seleccionada puede asociarse con una o más restricciones correspondientes a por lo menos uno del primer vector de movimiento o el segundo vector de movimiento. La estrategia de búsqueda de vectores de movimiento seleccionada se puede utilizar para determinar vectores de movimiento refinados con base en el primer vector de movimiento, el segundo vector de movimiento y las imágenes de referencia. El candidato de modo de fusión se puede procesar utilizando los vectores de movimiento refinados.
