摘    要:目的 针对医学图像非刚性点配准的现状,给出一种基于点特征的非刚性配准方法.方法 利用一种新的相似度测量方法--形状内容来解决两幅图像中点的对应关系,并利用点对应关系来估计非刚性映射函数.结果 利用薄板样条实现了医学图像的快速准确非刚性配准.结论 实验结果表明,上述方法获得了很好的配准效果.

关 键 词:非刚性配准  形状内容  薄板样条  点对应关系  形状  医学图像  非刚性配准方法  研究  Context  Shape  Spline  Based  配准效果  实验  快速  结果  映射函数  估计  对应关系  测量方法  相似度  利用  特征  现状

Abstract:Objective To present situation of medical image non-rigid registration, based on point-sets. Methods A new method to measure the similarity-the shape context was attached to solve the correspondences between points on the two shapes; and the correspondence was used to estimate the non-rigid transform function. Results The thin-plate spline was used to realize fast and exact non-rigid registration of medical image. Conclusion The experimental results show that this method can achieves better matching effect.
Keywords:non-rigid registration  shape context  thin-plate spline  point correspondence
