groundtruth

用matlab构建的信号发生器，其中包括交互界面，产生各种简单的波形，以及波形的混合叠加，以及外加音频的简单处理。交互界面中可以清楚看到波形的时域和频域的波形，包括波形的幅值，周期，功率均有图形显示(Constructed using matlab signal generator, including interface, simple treatment produces a variety of simple waveforms, and mixed superimposed waveforms, as well as external audio. Interactive interface, you can clearly see the waveform frequency domain and time domain waveforms, including the waveform amplitude, period, power has a graphic display )

这是一个经典的形变模型实施,在一个单一的文件用简单的可以理解的代码。 功能包括两部分一个简单的弱分类器和一个促进部分: 弱分类器试图找到最佳阈值的数据维数对数据进行分离成两个阶级1和1 要求的进一步提高分类器部分迭代,每一步是变化分类权重miss-classified例子。这造成了一连串的“弱分类器”,表现得像一个“强大分类器” (This a classic AdaBoost implementation, in one single file with easy understandable code. The function consist of two parts a simple weak classifier and a boosting part: The weak classifier tries to find the best threshold in one of the data dimensions to separate the data into two classes-1 and 1 The boosting part calls the classifier iteratively, after every classification step it changes the weights of miss-classified examples. This creates a cascade of "weak classifiers" which behaves like a "strong classifier" . )

说明：  这个是做模糊图像处理的一些例子，以及代码。各种方式去噪去模糊(This is to do some examples of fuzzy image processing, and code. Denoising a variety of ways to fuzzy)

说明：  使用matlabR2008a编写的多元逐步回归模型 经过调试(Prepared using matlabR2008a After debugging multiple regression model)

this paper is about the image watermarking using DWT+DCT+CDMA. it provides a good PSNR value then each technique seprately

自己用MATLAB/Simulink搭的三相电压锁相环模块，输出幅值相位和频率(Use their own MATLAB/Simulink take the three-phase voltage phase-locked loop module, the output amplitude phase and frequency)

说明：  matlab关于图形与图像的介绍，很不错，分享一下(matlab graphics and images on the introduction, it is good to share)
