提出了一种改进的加权Hausdorff距离，并将其应用于字符图像的匹配。该方法根据字符图像的结构特征对字符不同区域设置不同的权重。实践表明该方法改善了图像匹配效果。-An improved weighted Hausdorff distance, and applied to characters in the image matching. The method according to characters in the image of the structural characteristics of different regions of the character set different weights. Practice shows that the method improves the image matching results.
