The process of fingerprint identification can be divided into three steps: preprocessing of fingerprint images, feature extraction and feature matching.
指纹识别大致可以分为三个阶段：指纹图像预处理，指纹特征提取和指纹特征匹配。
To reduce the noise influence on fingerprint identification pretreatment, the process of fingerprint image is need, such as fingerprints image enhancement.
为减小噪声的影响，须在指纹识别预处理过程中对指纹进行优化，如进行指纹图像增强。
