An active camera tracking system (ACTS) is comprised of a camera that can rotate automatically toward an object of interest so the object remains within the camera’s field of view. To rotate the camera toward an object, the camera needs to detect the object’s location. Detecting an object’s location can be achieved using image processing techniques. However, conventional image processing techniques require expensive calculations in addition to expensive hardware, which in turn limits the video frame processing speed. In this paper, we propose an effective ACTS to monitor and track objects automatically with high accuracy. The proposed approach automatically initializes the object to be tracked using an absolute difference motion detection technique. To track the object correctly, the minimum output sum of squared error (MOSSE) adaptive correlation tracker is applied to provide an accurate and fast visual tracking. We also implemented an accurate scale estimation for the visual tracking technique that detects the scale changes of the object. Additionally, the proposed ACTS uses a closed loop controller to control the pan-tilt speed of the system. By combining these techniques, the proposed ACTS can provide accurate tracking with smooth rotation.
