说明：  一个Excel二次开发SDK接口类附代码。(An Excel secondary development SDK interface class with code)

hough变换检测直线代码在matlab下的运行(hough transformation)

实现数字图像的灰度范围的线性拉伸，对变换结果进行必要的分析，画出灰度变换曲线图，以另一个文件名形式保存灰度变换后的图像。(Achieve linear range of the gray range of digital images)

说明：  首先对指纹图像进行预处理，包括图像的分割，增强，二值化，细化。对细化后的图像进行特征点的提取，最后通过细节特征匹配完成指纹的识别。(Firstly, the fingerprint image is preprocessed, including image segmentation, enhancement, binarization and thinning. The refined image is extracted by feature points, and the fingerprint recognition is completed by minutiae feature matching.)
