任意精度的数学库

这是开放源代码的 ID3 算法使为我分配的代码。现在我在上传这段代码在这里获得的帮助形式的捐款。我将感谢全给他们会让这段代码动态，现在是静态的。

ECC加密算法实现C源码 ECC加密算法实现C源码 ECC加密算法实现C源码

根据sift flow的优点，利用sift的改进算法surf替代sift，实现surf flow。维数比sift 少，速度更快。利用matlab和c++混合编程实现，需要重新编译mex文件的cpp文件，利用matlab的mex编译技术完成。

该代码通过摄像头对动态的物体进行识别，发现有违章的或者闯红绿灯的返回信息，并在窗口处显示出来，如果没有违章的物体则不显示出来。

计算矩阵行列式值的源程序-calculating the determinant of the matrix source

EM算法，基于期望最大化原则进行密度估计-EM algorithm, based on the expectation maximization of the principle of density estimation

we propose a generative tracking method based on a novel robust linear regression algorithm. In con- trast to existing methods, the proposed Least Soft-thresold Squares (LSS) algorithm models the error term with the Gaussian-Laplacian distribution, which can be solved ef- ficiently. Based on maximum joint likelihood of parameters, we derive a LSS distance to measure the difference between an observation sample and the dictionary. Compared with the distance derived from ordinary least squares methods, the proposed metric is more effective

Multiband_Kamath.m Description: Multiband spectral subtraction as proposed by Kamath 2002. Uses adjusts the subtraction coefficient with the frequency as well as the SNR. note that the first 0.25sec of your signal is used to model the noise.
