代码说明:

  在指纹特征提取中,结合方向图和图像局部灰度方差对指纹图像进行分割,然后再进行阈值分割去处边缘效应得出较好的分割结果。(In the fingerprint feature extraction, the combination of pattern and image local variance of gray-scale fingerprint image segmentation, and then conducted threshold segmentation edge effects come to a better place for the segmentation results.)

  • HarrisCorner
    对输入的一张彩色图像,自己写代码实现Harris Corner 检测算法: 1. 不能直接调用OpenCV 里面与Harris 角点检测相关的一些函数; 2. 只能用C/C++,不能用其他语言; 3. GUI 只能用自带的HighGUI,不能用QT 或其他的; 4. 平台可以用Windows, Linux, MacOS; 5. 显示中间的处理结果及最终的检测结果,包括最大特征值图,最小特征值图,R 图(可以考虑彩色 展示),原图上叠加检测结果等,并将这些中间结果都输出成图像文件; 6. 命令格式: “xxx.exe 图片文件 k 参数(=0.04) Aperture_size(=3)”。(The input of a color image, write your own code to achieve Harris Corner Detection Algorithm: 1. Can not be called directly inside OpenCV some functions associated with the Harris corner detection 2. To only use C/C++, can not be used in other languages 3. GUI only with their own HighGUI, can not use QT or other 4. The platform can be used Windows, Linux, MacOS 5. Display intermediate and final results of the test results, including the largest eigenvalues diagram, the minimum feature value graph , R chart (you can consider color display), picture superimposed on the test results, etc., and these intermediate results are output as an image file 6. Command Format: " xxx.exe picture file k parameters (= 0.04) Aperture_size (= 3 ). " )
