Application of Chamfer Matching in the Registration of CT and MRI ChamferMatching在CT和MRI图像匹配融合中的应用
In the process of feature character comparison, some methods for character comparison are presented which are chamfer matching, the texture feature of gray matrix and texture analysis using Wigner distribution. 在特征字的特征提取过程中,对字符的形状特征,运用距离变换匹配的方法;对字符的纹理特征,采用基于游程矩阵的分析方法和Wigner分布的分析方法。
On the base of point cloud preliminary matching with PCA, a data matching algorithm based on feature extraction of chamfer distance is proposed to further improve the point cloud matching precision. 在采用主成分分析法进行点云初步匹配的基础上提出一种基于Chamfer距离特征提的数据匹配算法,进一步提高了点云匹配精度。
