Abstract :
A high-speed compact digital correlation tracker which determines the frame-to-frame translational motion between two images is presented. By combining a similarity detection approach with the correlation coefficient in a parallel pipelined architecture, effective tracking rates comparable to conventional fast Fourier transform (FFT) techniques can be achieved. Examples of the tracker´s performance using simulated data and image data acquired by an active infrared radar are given.
