| Abstract: | The effect of fingerprint enhancement had influence on the character-extracting and the accuracy of Real-time Fingerprint Recognize System.Because its advantage in direction-selectivity and frequency-selectivity,Gabor filter is broadly applied in fingerprint enhancement.In this paper,we introduce a new algorithm of fingerprint enhancement which is based on Half-Gabor filter bank.By validated on TMS320VC5409,the effect of fingerprint enhancement is proved. |
