Monitoring and Movement Detection Using Image Subtraction Method

Monitoring and movement detection system is a system that is used to detect changes made by the person or object. Those changes may be either abnormal behavior or unusual changes that are done by the person or by the object. We use consecutive frames comparison with image subtraction method in our research work. We subtract R,G and B value of the two consecutive frame pixel by pixel which gives us better result compare to others. By using this we extract the little movement in the real time video or any recorded video. In this technique, we have to arrange a high quality camera that will monitor. This camera will save the different frames taken at different point of time. These frames can then be analyzed by the user at a later point of time. This research work is very helpful for video surveillance, security purposes, patient movement detection and for anywhere we want to detect movement. Because in many situations, only a minor movement made is detected plays an important role.The algorithm is implemented in MATLAB and the results demonstrate that the accuracy is very promising. The algorithm can be used in video based applications such as automatic video surveillance, motion-based recognition or anywhere we want to detect the movement of person or object. In this it gives us the percentage of movement detection w.r.t time and it also generates an alarm to notify the user for some unusual movement.
