| 摘 要： | 文中提出了一种新的图像配准方法,可以很好解决图像配准中的平移和旋转问题(刚性变换问题)。算法的实现是首先得到待配准两幅图像的轮廓特征点(本文使用SUSAN边缘检测算法);再剔除虚假的特征点(噪声点)后,根据像素间的连通性判别准则,得到图像的主轮廓;最后以两幅图像的主轮廓信息,配准图像。实验证明,算法实现速度快,精度较高。

| Abstract: | A new algorithm about image registration is presented in this paper, which has solved translations and rotations transformations (so-called rigid transformations) problems in image registration process well. This approach is as followed: first, we use SUSAN edge-detected method to obtain the feature points (interesting points) of the two images, and from which, we eliminate the bad-feature points (the noise points); second, by using connectedness-judged criteria, acquire the main outlines of the two images; third and last, we use the information extracted from the main outlines to register the two images. The experiments have test the effect of the approach. |
