Abstract :
This paper introduces a real-time TV tracking system which is based on DSP (DM642). It narrates the principle of hardware design and the structure of the hardware in detail. A fast median filter algorithm, which is the most novelty in the system, is used to achieve the image pre-processed. And the algorithm of centroid calculated and Gaussian-fitting predicting approach are used to track the target. The experiment proves that this system can obtain continuous and stable tracking effect when the target is moving and covered up.
