摘要
介绍了指纹识别的处理步骤 ,提出了一种基于细节特征匹配的自动指纹识别算法 ,分别给出了图像预处理、二值化、细化、纹路提取、确定指纹中心点以及指纹匹配的特征和算法步骤 。
The processing steps of fingerprint recognition are introduced,one algorithm of automatic fingerprint recognition on directional fields is put forward,then the preprocessing,binarizing,thinning,picking up fingerprint threads,picking up minutiae feature,fingerprint matching and algorithms are educed,at last,its validity is proved by experiment.
