This program denoises an image based on soft-thresholding wavelet coefficients with the so-called universal thereshold, Visushrink. Only the wavelet coefficients are thresholded.

基于svd的数字水印，信噪比比较高(Svd based digital watermarking, can also signal to noise ratio is relatively high)

这是一个分类和回归树算法，它提供一种通用框架将各种各样不同的判定树实例化。(This is a classification and regression tree algorithm, which provides a common framework a wide variety of different decision tree instantiation.)

说明：  广义预测控制应用于预测控制，可以根据个人需要进行变换(GPC)

本程序可实现bootstrap算法的matlab编程，以M文件形式。(This procedure can be realized bootstrap algorithm matlab programming to M file format.)

gibbs算法示例，在统计学和统计物理学中，gibbs抽样是马尔可夫链蒙特卡尔理论（MCMC）中用来获取一系列近似等于指定多维概率分布（比如2个或者多个随即变量的联合概率分布）观察样本的算法。(Example of Gibbs algorithm)

说明：  虽然 AdaBoost 算法的检测速度快，误识率低，但是在样本的权重更新过程中，对于分类错误样本中的正、负样本没有加以区分，不利于提高正样本的识别率。本文提出一种新的权重更新方法，对于分类错误的样本，对判断错误的正样本给更高的权重，使得算法在下一轮迭代时，更加关注对分类错误的正样本的学习，从而提高对正样本（人眼）的检测率。采用基于最小二乘法对眼部的外轮廓进行椭圆拟合，根据拟合椭圆的参数来判断眼睛的睁闭状态；采用结合 PERCLOS 和眨眼频率的方法，对疲劳状态进行检测。(Although AdaBoost algorithm has fast detection speed and low false recognition rate, in the process of sample weight updating, there is no distinction between positive and negative samples in classification error samples, which is not conducive to improving the recognition rate of positive samples. In this paper, a new weight updating method is proposed, which gives higher weight to the positive samples of classification errors, so that the algorithm pays more attention to the learning of the positive samples of classification errors in the next iteration, so as to improve the detection rate of the positive samples (human eyes). Based on the least square method, the eye contour is fitted with ellipse, and the opening and closing state of eyes is judged according to the parameters of fitting ellipse; the fatigue state is detected by combining PERCLOS and blinking frequency..)
