Target Tracking Using Multiple Templates Based on Maximum Pixel Count Criterion

Usually, we use a single template in traditional template matching. But single template is affected easily by geometric distortion. The distortion of some pixels would affect the whole template. For solving the problem, in this paper we divide the original template into five small templates. The small template has fewer pixels than the original template; geometric distortion just affects the relevant small template. We match the other templates with the image by a new matching method based on the improved maximum pixel count (MPC) criterion which considers not only the number of similar points but the error value. Experimental results demonstrate that the method proposed in this paper has better accuracy, precision, robust.
