Applying image processing technology to monitor the disabilities’ security

In order to enhance the disabilities’ security all alone at home, a way of home care services for detecting the disabilities whether they tumble or not is proposed in this paper. This experiment is mainly applied for detecting the disabilities and avoiding the accidents in daily life all alone. In this paper, the system combines the image tracking technology with the image subtraction of the original background image and the current image which are from camera to identify the moving objects. Then, it make the detecting identification for human body in daily life and mark it as region of interest (ROI) to differentiate from other objects which regard as background or obstacles. Furthermore, it can judge whether the human body lie down or not. Also, it can judge the area where the human bodies lie down is proper or not. The system will give the alarm once it judges the abnormal phenomenon that the human body lies down. According to the consequence of the experiment, this system obtains a satisfactory outcome and accuracy from the algorithm.
