fingerprint-classification1

基于互信息的刚性配准，利用了Powell算法和黄金分割算法，效果还不错(Based on Mutual Information rigid registration, Powell algorithm and the use of the golden section algorithm, the results were good)

一个很好用的bmp图像转protelPCB封装库，如果有需要在pcb中插入图像，汉字的朋友可以下载(bmp to protel99，it s a good tool，welcom to download)

基于ransac的椭圆检测，对于一组随机的椭圆点，可以得到椭圆参数，检测精度高。(Based ransac ellipse detection, for a group of random elliptic points, you can get an ellipse parameters, high detection accuracy.)

阴影消除matlab代码，运行可用，可供参考(The shadow eliminates the matlab code, which is available for reference)

说明：  图像的重心区域检测 matlab程序实现 可以检测重心区域并设置成希望颜色，对单景物背景图像效果极佳(regional focus image detection Matlab program can detect regional focus and set hope that the color of single features excellent background images)

指纹灰度图像的matlab代码，文件附带指纹图像(Gray-scale fingerprint image matlab code, documents attached to the fingerprint image)

区域邻接图的合并规则，在进行区域合并时可以使用，希望对大家有用(region merging for region adjecent gragh，might it be help for you.)

1.图像尺度转换，降低图像分辨率，采用局部平均法、中值法；2.图像质量评价：均值、标准差、信息熵、平均梯度(1.Image scaling, reducing image resolution, using a local average、median method；2.Image quality assessment: the mean, standard deviation, entropy, average gradient )

Matlab数字图像处理,GUI界面,可以运行,载入图象后进行变换(Image traslation based on Matlab)

最小二乘法拟合圆vc实现，最小二乘法(least squares analysis)是一种 数学 优化 技术，它通过 最小化 误差 的平方和找到一组数据的最佳 函数 匹配。 最小二乘法是用最简的方法求得一些绝对不可知的真值，而令误差平方之和为最小。(least squares fitting round vc realized, least-squares method (least squares analysis) is a mathematical optimization techniques, It error by minimizing the square and a group of data to find the best matching function. Least-squares method is the most simple method to derive absolutely true value unknown, and so the sum of squared errors to the minimum.)
