| 摘 要： | 针对现有的指纹增强算法中图像分割不彻底,不能很好地修复指纹断裂纹线问题.以分形理论为基础,利用差分计盒维数算法与Gabor滤波器增强方法,通过计算指纹图像的方向场和频率场,设计了一种指纹图像增强算法.实验结果表明,该算法提高了指纹图像的处理速度,对断裂处的指纹脊线有很好的修复效果. |

| Abstract: | As the fingerprint enhancement algorithm in the existing image segmentation is not complete and cannot repair the broken crack line fingerprint problem well,we take the fractal theory as the foundation,use differential box counting algorithm and the Gabor filter enhancement,through the computation fingerprint image's field of directions and the frequency field,and has designed a kind of fingerprint image intensification algorithm.The experimental result indicated that this algorithm raised the fingerprint i... |
