摘要
指纹具有唯一性、稳定性、再生性等特点。指纹识别技术为现代身份识别提供了一个很好的解决方案。指纹识别算法一般包括预处理和特征提取与匹配两大部分。其中预处理通常包括图像分割、图像滤波、图像增强、图像二值化以及图像细化等步骤。文中主要对以上各个步骤在PC机上用Visual C++编程实现,并给出了各个步骤的实验结果。实验结果表明,采用VC++平台实现指纹识别算法简单实用,指纹图像处理效果较好。
Fingerprint has characteristics of unique, stable and reborn. Fingerprint recognition technique provides a very good scheme to modern identity recognition. The algorithms of fingerprint recognition consist of preprocess, feature extraction and matching commonly. And preprocess consists of steps： image segmentation, image filtering, image enhancement, image bi-value and image thinning. These steps are realized on PC using Visual C＋＋ , and the experiment results are shown. The results demonstrate that it is simple and practical to implement fingerprint recognition using VC＋＋ flat and the effects of fingerprint image is perfect.
