Besides in order to erase the influence of camera moving , we applied a approach to registry image by matching characteristic points in the image 此外为了消除摄像机本身晃动的影响，本文使用了一种基于特征点匹配的图像配准方法。
To resolve those problems mentioned above , in this paper the authors propose a global matching method based on combination of feature point and feature edge 为更好地解决上述问题，本文提出了基于特征点匹配与边缘线匹配相结合的方法。
Design digital filter , demarcate the feature points of ecg wave with the traditional ecg analytic algorithm and analyze the heart rate 设计了数字滤波器，并利用传统的心电分析算法，对波形的特征点进行了标定，并分析了心率参数。
