使用低通滤波器，观察原始图像与以图形形式显示的高斯低通滤波器的差别，显示频谱和处理后的图像！(Using low-pass filter to observe the original image and displayed in graphical form of the difference between the Gaussian low pass filter, display the spectrum and the processed image!)

non linear B spline curve fitting

iRobotCreateSimulatorToolbox1_3 iRobot仿真matlab工具箱(iRobotCreateSimulatorToolbox1_3 iRobot simulation matlab toolbox)

AR模型参数确定后计算出功率谱, 用Levision_Durbin 算法(AR model parameters were calculated to determine the power spectrum, using Levision_Durbin algorithm)

ask、psk、fsk等的产生波形的matlab程序，还不错()

说明：  图像压缩，主成分分析的应用介绍，很有用啊(Image compression, principal component analysis applications introduced useful)

非高斯有色噪声中的谐波回复的方法研究，主要是SVD_TLS方法。(Methods of non-Gaussian colored noise harmonic restoration )

LDPC在BPSK考虑AWGN信道下，采用软判决和积算法的仿真。这是第一个(LDPC in AWGN channel BPSK considering the introduction of soft-decision and the plot of the simulation algorithm. This is the first)

这是我自己写的对图像进行预处理的matlab源程序，主要是对图像进行光照补偿、旋转与尺度归一化。上传上来和大家一起学习、分享。(This is I wrote it myself pretreatment image matlab source, mainly for image illumination compensation, rotation and scale normalized. From up and study together, to share.)

Fixed 7/17/93 to use inverse-hessian instead of hessian itself in bfgs
