| 摘 要： | 本文提出了一种基于改进的Gabor函数小波域指纹增强算法。该算法对Gabor滤波器的标准差和滤波器的大小由传统的固定值,改为指纹脊线频率函数,能充分利用图像本身信息对图像增强处理。实验表明,改进的算法使指纹图像得到了明显的增强。

| Abstract: | This paper introduces a improved gabor function-based fingerprint image enhanced algorithm in wavelet domin. The algorithm optimized standard deviation and filter window size, and then defines as a function of frequency, this filter can make full use of the original image information to enhance the image. Simulation results on some typical images show that our proposed algorithm can enhance the fingerprint effectively. |
