We introduce an automatic fingerprint classification system, where filters are based on two types of Fourier Transform(FT)for enhancing fingerprint images, and a probabilistic neural network classifier is used.

• 本文介绍了一个基于两种傅氏变换进行图像增强,用概率神经网络进行指纹分类的指纹自动分类系统,又称AFCS(Automatic Fingerprint Classification System)。
