| 摘 要： | 针对指横纹感兴趣区域(ROI)难以准确、快速定位的问题,提出了利用降维比较进行定位的方法。该方法在图像定位阶段,对ROI特征图像在水平和垂直2个方向投影,实现了图像的降维,在保留特征信息的基础上降低了后续处理计算的时间复杂度。将降维后的2个一维向量进行比较,最终实现指横纹ROI的精准定位。相对于传统方法,本方法降低了运算的维数,算法复杂度低,速度快,实验结果验证了该方法的有效性。 |

| Abstract: | Considering the difficulty of accurately and fast location of ROI of inner-knuckle-print, a new location algorithm is presented forward based on dimension reduction. This algorithm transforms 2-dimension image data to two 1-dimension data by projecting the binary image in vertical and horizontal direction, and then aligns ROI images through the comparison of the two 1-dimension data. This leads to rapid and efficient recognition. The experimental results verify that it is rapid and effective than traditional methods. |
