| 摘 要： | 文章主要阐述指纹图像自动无损提取的实现问题．首先讨论了如何利用指纹卡中边框的结构特性，将原始图像分割成十块区域，并使其中的每块区域均含有一枚指纹．然后，进一步分析每块区域中指纹区的灰度分布、面积等特性，在借鉴和改进模糊化、二值化、求取最大连通域和指纹形心等算法的基础上，增加了目标膨胀、对含有重叠边框线的后处理等算法．

| Abstract: | The article mainly elaborates the realization of automatic extraction of the fingerprint image without any damage. At first, it discusses how to make use of the structural feature of the frame on the card, how to divide the original image into ten parts and make every part contain one fingerprint. Then, analyzes further the feature of gray degree distribution and its area of every part. After referring to and improving the calculation method of obscurification, double valuing, obtaining maximum coherence area and finger print center, it adds the calculation method of object expansion, post-treatment on contained overlapping frame lines. |

| Keywords: | fingerprint image object expansion post-treatment of the fingerprint image lossless extraction |
