Surfer是地学中常用的一个软件，可以完成等值线图，立体图，流向图等的汇制。其自带的类VBA的开发语言，可以进行二次开发。附件是一些源程序。其中的Jackknifes可以用来对比不同的内差方法，从而得出最优化的内差方法。 (Surfer is the study of a commonly used software, complete contour map, a three-dimensional map, map the flow of the system. Its built-in categories VBA programming languages that can be re-developed. Annex some source. Jackknifes which can be used for comparison within the poor, so as to come up with the most optimal way worse.)

实现均值滤波，中值滤波，小波去噪三种不同的高斯噪声和椒盐噪声的去除(to deal with noise of gaosi and jiaoyan)

用Jacobi迭代法计算大型方程组的MATLAB函数文件(Jacobi iterative method using large calculation equations MATLAB function documents)

Min/Max filter，最大最小滤波器，说明看英文，只是国外的人写的代码， (Description The filter computes the minima and/or maxima of an array over sliding window with a given size. Multidimensional array is fully supported: running filter in 1D, 2D filter for image processing applications (erosion/dilatation), 3D and more. This package has been implemented with a special care on the running speed: the MEX engine uses an algorithms that requires no more than three (3) comparisons per element and per dimension in all configurations. All numerical and logical class arrays are supported. Contributor (beside author) is Vaclav Potesil Acknowledgements This submission has inspired the following: Free-knot spline approximation MATLAB release MATLAB 7.8 (R2009a) Other requirements MEX correctly setup NO image processing is required Download a tiff file for )

This is a matlab file for finferprint recognition

this is a code to calculate the moment invariant of images. the values which come out are capable of removing rotational, scaling, transnational variation in image given as input.classification can be done with the help of it.

功能为neighborhood components analysis，a quick matlab implementation of NCA (see Goldberger et al, NIPS04). (err)

sift的matlab代码，是最新的,效果不错，其中有很多详细说明，可以试试。(sift the matlab code, is the latest, well, there are a lot of detail, you can try.)

最优化算法DFP算法源代码 可以实现求极小值的(dfp program orginal file)

能量检测,主要是看如果根据虚警概率得到门限，然后进行判决(enengy detection)
