基于Hausdorff距离的SAR图像匹配方法

摘要

Based on the conventional Hausdorff distance matching of edge position,we introduced the information of edge gradient direction to distance measuring. We constructed a new distance function that used the information of edge position and gradient direction, and used it to the SAR image matching. Experimental result shows that the robustness of the proposed algorithm has been improved compared to conventional algorithms.%在传统基于边缘位置的Hausdorff距离匹配基础上,将边缘点的梯度方向信息引入到距离度量中.提出了一种新Hausdorff距离及相应的匹配算法,并将其应用到SAR图像匹配中.实验表明,该算法相对于传统的基于边缘位置的Hausdorff距离匹配算法鲁棒性有所改进.
