Image Correlation Based Video Tracking

Image correlation can be used for quality testing, pattern recognition, image searching, and image tracking. Image tracking of a video image was the focus of a frequency domain based approach using two-dimensional Fourier transforms for image correlation. When tracking a moving object that varies in size over time, a technique to identify the position of a template image within the larger picture was used. This approach requires the dynamic resizing of the template image in the video as it grows and shrinks in size. This approach allows for accurate image placement and the subsequent path of the image through a video screen can be followed. The solution can be implemented to provide real time results to provide the path of the image tracked.
