Real time detection of moving human based on digital image processing

Energy saving becomes a significant issue in recent years. There are two conventional methods of using the infrared ray sensor and CCD camera to detect human movement. The method of using the infrared ray sensor, however, frequently causes malfunction problems. On the other hand, the method which uses CCD camera requires accompanying high price equipments. To save electric energy, this paper proposes an algorithm to recognize human presence with USB Web camera. The proposed algorithm detects human movement using the circle detection and morphological methods. Under various experiments, the proposed method shows better performance in terms of the recognition rate and speed.
