实现功率谱密度分析psd及详细解说

MATLAB工具结合数字图像处理，完成实验，有图像彩色空间转换，傅里叶变换，余弦变换，直方图均衡等等，有需要的看一下。(Combination of MATLAB tools for digital image processing, the completion of the experiment, the image color space conversion, Fourier transform, cosine transform, histogram equalization and so on, there is a need to look at the.)

提供了二阶块稀疏算法，该算法特别适合于压缩感知

power systems-lamda iteration

DCT 3D function for signal

小波模极大源代码，可用来进行小波降噪或小波模态参数识别，该代码为斯坦福大学源码。(wavelet modulus maxima source code, which can be used for wavelet denoising or wavelet modal parameter identification, The code for the source of Stanford University.)

本代码包含遗传算法matlab工具箱中部分代码，与GAmat1.rar，GAmat2.rar，GAmat3.rar共同使用(This code contains the genetic algorithm matlab toolbox, part of the code, and GAmat1.rar, GAmat2.rar, GAmat3.rar common use)

说明：  相位解包裹.我们可以从中获取波免从干涉图中(Phase unwrapping. From which we can get free from the interference pattern of wave)

说明：  采用BP神经网络算法进行调制样式识别的Matlab代码(Using BP neural network pattern recognition algorithm Matlab code modulation)

说明：  IBD算法源代码 能够让初学者很好的了解IBD算法(blind image restoration)
