中文摘要：

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。

英文摘要：

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.
