| 摘 要： | 目的:针对特征图像配准方法速度快、效率高,而医学图像具有结构信息不明显、变形复杂等特点,该类方法常常失效,提出一种结合SURF特征与图像边缘信息的配准方案.方法:首先使用SURF法检测图像的特征点,采用角度法判断特征点是否匹配错误,并将误匹配的特征点删除；然后,将所得特征点对与图像的Canny边缘相结合,形成一个新的特...

| Abstract: | Objective: For the fast and high efficiency of image registration methods for features,they often fail in medical image registration because the structural information of medical images are not obvious and the deformation of medical images is always complex,a method combined SURF features and edge information is presented for image registration.Methods: First,the SURF is used for features detection.Then the mismatched points are found and deleted according to the angles between features.Next,the obtained fe... |
