Abstract
Un método ejemplar de procesamiento de video incluye determinar, para una conversión entre una imagen actual de un video y una representación codificada del video, una posición de una muestra de referencia en una imagen de referencia que está asociada con la imagen actual con base en una posición superior-izquierda de una ventana de una imagen. La imagen incluye al menos la imagen actual o la imagen de referencia, y la ventana se somete a una regla de procesamiento durante la conversión. El método también incluye realizar la conversión con base en la determinación.
