图像匹配的鲁棒型Hausdorff方法

Image Matching Based on Robust Hausdorff Distance

  • 摘要: 提出基于一种新型Hausdorff距离的鲁棒型图像匹配方法.首先对传统的各种Hausdorff距离所存在的缺陷进行了分析,然后根据这些缺陷提出了"鲁棒型"的Hausdorff距离.这一新的距离考虑了边缘点的位置、边缘点的总数、由有限点组成的伪边缘、出格点和边缘的遮挡等因素,从而使传统的缺陷得到了克服.对合成图像及实际图像的实验结果表明,所提出的Hausdorff距离测度比传统的Hausdorff距离测度更为有效.

     

    Abstract: Limitations of conventional Hausdorff distance (HD) measures are analyzed. Then focusing on these limitations, the robust HD measure is proposed that takes into account the image factors such as position and total number of edge points, spurious edge segments containing a very limited number of edge points, outlier points, and edge occlusions. As a result, the limitations of conventional measures are overcome. Experiment results for both synthetic and real images show that the proposed HD measure is more efficient than the conventional HD measures.
