| 摘 要： | 研究指纹增强技术对于提高指纹特征提取的准确率乃至整个自动指纹识别系统都具有重要的意义。本文利用加博滤波具有良好带通滤波的特性,对指纹图像进行去噪处理,再使用纹线投票算法获取指纹图像的纹线结构,由此提取指纹图像的方向信息,并在此基础上对图像进行了增强处理。实验结果表明,指纹图像增强效果显著,可满足非实时性自动指纹识别系统的要求。

| Abstract: | Fingerprint image vary in quality.To poor quality to reliably extract minutiae directly,in order to Gabor filter has good band-pass property.This paper studies on noise removal for low quaiity fingerprint images and acquires ridge construction with ridge voting algorithm.Directional in formation is acquired and is combined to enhance fingerprint images.Results indicate that the method has dramatic enhancing effect on low quaiity fingerprint images and can used in non-real time AFLS (automatic fingerprint identirication system). |
