摘要
在指纹识别系统中,指纹图像预处理是指纹特征提取与识别的前提.对指纹图像预处理技术进行了研究,提出了一种指纹图像预处理算法.实验结果显示,该算法能够去除指纹噪声,得到较高质量的指纹图像.
In fingerprint recognition system, the image preprocessing is the precondition for extration and recognition of fingerprint characteristics. Based on the research of fingerprint pretreatment technology, this paper proposes a preprocessing algorithm of fingerprint image. The experimental results show that the method can eliminate the noise in fingerprint image and get fingerprint image with high guality.
