Image enhancement using dwt

对信号进行傅里叶变换，并绘出频谱图，功率谱，对数谱等。然后对信号进行反傅里叶变换恢复出原始信号，并绘出其各种谱图(The Fourier transform of the signal, and plot the frequency spectrum, power spectrum, the number spectrum. And inverse Fourier transform to recover the original signal and plot its various spectrum signal)

这个文件是一些图像去模糊的实例，值得我们一起学习。(This file is some Blur instance, it is worth to study with us.)

converts a a number to fixed point qmn format using matlab

说明：  实现粒子群算法的pid整定，适应于simulink模型的仿真，效果不错(Realize the pid tuning of particle swarm optimization algorithm, adapt to the simulation of simulink model, the effect is good)

帮住MATLAB初学者学习该软件，适合入门学习。(easy MATLAB)

这个是我个人编写的短时傅里叶变换的函数matlab.适用于语音压缩与语音分析.在其中可以加入一些自己的代码，即可改成phase vocoder(this is the STFT function which is wrote by myself(matlab). It is suit for speech compression and analyse. if you add some code in it, it can turn to a phase vocoder straightforward. )
