摘要
该文提出了一个新的匹配准则——特征点对齐度准则,并在此基础上提出了一种基于特征点对齐度准则的图像配准方法。首先,利用小波多尺度积提取出图像的特征点及其角度信息,再利用该文提出的特征点对齐度准则计算所有特征点对之间的对齐度,从而得到匹配点对。实验结果证明了该方法的精确性和有效性。
A new matching metric alignment metric of feature points is defined, and a new approach to image registration based on alignment metric of feature points is proposed. Feature points and their angles are detected by using wavelet multi-scale product, then the alignment metric of all feature points are calculated, so matching points can be obtained. The experimental results illustrate the algorithm has a good performance of accuracy and efficiency.
