摘要
根据一维递归Gabor滤波算法设计了二维RGF(Recursive Gabor Filtering)算法,通过实验论证了RGF不仅与Gabor滤波等价,而且速度更快。在此基础上提出了RGF方法代替传统的Gabor滤波器方法应用到指纹特征提取,并用实验论证了参数的选择。实验结果显示该方法的有效性,具有很高的实用价值。
2-D recursive gabor filtering（RGF） algorithm is designed according to 1-D recursive gabor filtering algorithm, h is proved byexperiment that RGF is not only equal to Gabor filtering, but its speed is faster As a substetute for traditional Gabor filterbank method, RGF- based method is proposed to extract fingerprint feature. Parameter selection is given by comparing different parameter effect, The result of experiment shows that the algorithm is effective and has high value practicality.
