摘　　要：在实时指纹识别系统中,指纹图像增强的效果好坏将影响特征提取及指纹鉴别的识别率.Gabor滤波器由于其方向选择性和频率选择性的优点,在指纹图像增强中得到了广泛的应用.本文介绍了基于半Gabor滤波组的指纹图像增强算法,通过在TMS320VC5409上的验证证明该算法具有良好地指纹图像增强效果.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.
