- 指纹图像的分类Fingerprint classification using fast Fourier transform and nonlinear discriminant analysis
Automatic_Fingerprint_Authentication_System
- A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed. A fingerprint image is preprocessed to enhance the image by Short Time Fourier Transform (STFT) analysis. Then, three sets of invariant moment features, as a kind o
