Chen recalls, "At that time there was only one image processing system in Taiwan, and it was very expensive. It was placed in our center, but was open for use by all research units in the country. Our own researchers often had to wait until late afternoon or evening just to use it."
影像處理系統也不像現在這麼普及，「那時全台灣只有一部影像處理系統，貴得很，就擺在我們中心裡，開放給全國的研究單位使用，我們自己的研究人員都要等到下午或晚上才能使用」，陳哲俊回憶說。
