基于Gabor滤波指纹图像增强方法

Research on Fingerprint Image Enhancement Method

图像增强是指纹自动识别系统中非常关键的部分,它直接影响着指纹识别的最终效果。指纹预处理一般包括规格化、方向图计算、频率计算,图像分割、增强等环节,给出一套完整的增强算法,实验证明,这些算法处理效果好,运行速度快,具有很高的使用和参考价值。

Fingerprint enhancement plays a key role in the fingerprint identification system, which directly influences the final accuracy of fingerprint identification. Fingerprint enhancement usually includes five steps： normalization, directional graph computation, frequency computation, segmentation, enhancement a fingerprint image enhancement algorithm is proposed in tiffs paper.The experiments show that these algorithms have the advantages of good processing effcct and fast operating speed. They have high value both in practice and in reference.
