| 摘 要： | 指纹图像增强在指纹图像预处理过程中有着非常重要的作用,直接影响指纹识别的识别率和识别速度。一般图像增强算法无法满足指纹识别系统的要求,为了提高指纹增强算法的综合性能,现提出一种优化的Gabor滤波方法以增强指纹图像并有效消除噪声,并对Gabor滤波器的参数进行量化。实验表明,该算法能够使图像的质量明显得到增强,方便了后续指纹特征的提取,以提高指纹识别的算法效率和准确率。

| Abstract: | Fingerprint image enhancement has very important using in the preprocessing of the fingerprint image.It is directly restricting the recognition rate and speed of fingerprint recognition.Ordinary image enhancement ways can't fill fingerprint identification system,to improve the ability of fingerprint image enhancement way.A method is presented to enhance fingerprint image and to eliminate noises effectively with optimal Gabor filters.As well as quantify the parameters of filter.Experimental results show that... |
