The paper introduces briefly the characteristics of afit , the significance of the fingerprint image pre - processing and all parts of afis ( automatic fingerprint identification system ) , then expatiates on the image pre - processing included image segmentation , image enhancement , image binarization and thinning
本文首先简要介绍了指纹识别技术的特点、指纹图像预处理技术意义及自动指纹识别系统的流程,然后主要阐述了指纹图像预处理中的图像分割、图像增强、图像二值化及细化等部分的算法实现。
It is very important for minutia extraction in afit ( automatic fingerprint identification technology ) based on minutia matching . the fingerprint image always has much noise and can not be adapted to extract minutia directly , so pre - processing of fingerprint image to get a point - line image is an important part of afit domain
细节特征点的准确提取在基于细节特征点匹配的自动指纹识别技术中十分重要,然而由于各种噪声的影响,使得所采集的指纹图像质量比较差,并不适合直接用来提取细节特征点,所以对指纹图像进行预处理以获得清晰的点线图是自动指纹识别研究领域的一个重要组成部分。
