| 提出了一种基于傅里叶变换的双级匹配掌纹识别系统.首先提取掌面的最大内圆作为识别的有效区域,利用该内圆的半径进行第一级匹配.然后对提取出的区域进行傅里叶变换,统计出频域图像的能量分布模式进行第二级匹配.实验表明这种双级匹配的识别方法实现简单,操作方便,同时具有较快的反应速度和较低的误识率. |
| 英文摘要: |
| In this paper,we propose a palmprint recognition system using two-stage match method based on Fourier transform.First we extract the maximum inscribed circle of palm as the region of interest,then use the radius of this circle to carry out first-stage match.Then we do Fourier transform to the extracted region,and calculate the power distribution mode of the frequency-domain image to perform second-stage match.The result of experiment shows the two-stage recognition method is simple to realize,and has advantages of handy operation,fast responding velocity and low false recognition rate. |
