| 摘 要： | 提出了一种自适应跟踪算法,其主要思想是用六个仿射变换参数来表征图像中目标区域的运动,由当前位置图像与模板图像的差分图像可以求取这些参数,并进一步用这些参数来预测目标的运动和跟踪目标。在实际跟踪过程中,又采取一种有效的相似性度量方法,用它来决定是否修改模板,以及如何修改。

| Abstract: | In this paper, a new approach to track rigid objects is presented. The affine transformation method is built and extended. The matching problem which few parameters are used to represent the transformation between the image and the template is formulated. On the basis of the similarity measurement, a suitable template updating template strategy is proposed. By using these techniques to track objects over several long image sequences, the experimental results show that this image matching method can bear affine image motions and image distortion to some extent and the stability of the algorithm is improved greatly in this way. |
