A simple Algorithm for motion detection by a fixed camera compares the current image with a reference image and simply counts the number of different Pixel s. Since images will naturally differ due to factors such as varying lighting, camera Flicker , and CCD Dark Current s, pre-processing is useful to reduce the number of False Positive alarms. More complex algorithms are necessary to detect motion when the camera itself is moving, or when the motion of a specific object must be detected in a field containing other movement which can be ignored. An example might be a painting in an Art Gallery surrounded by visitors. When motion detection is accomplished by natural organisms, we speak of Motion Perception . References |
