| Abstract | ||
| Fingerprint image enhancement is very important step in fingerprint recognition system .choosing the right method can be very critical point due to its effect on the performance of the feature extraction operation. This paper will present three main method (histogram equalization method that enhance the fingerprint image by adjusting the grey scale level contrast of the fingerprint image, FFT transform that enhance the finger print image base on its frequency domain and Gabor filter that enhance the fingerprint image based on its directional and frequency estimation map) The evaluation of the three enhancement method will be based on the analyzing the performance of feature extraction operation after applying the three methods. | ||
