matlab图像处理实例详解chap6——图像复原技术(matlab image processing example explanation chap6- Image Restoration)

1、系统仅处于训练状态。训练序列为2cos(2π×f1×n/fs)， 干扰为sin(2π×f2×n/fs)；序列长度为100个样点。 其中n=0…99，f1=1kHz，f2=2kHz，fs=8kHz。 2、采用LMS算法，均衡器输入为训练序列加上干扰，均衡器阶数为21阶，步长因子β=0.01。 3、在Matlab中编写浮点LMS算法，绘制均衡器的输出波形，并与训练序列进行对比。 (1, the system only in the training status. The training sequence is 2cos (2πf1n/fs), interference sin (2πf2n/fs) sequence length of 100 samples. Where n = 0 ... 99, f1 = 1kHz, f2 = 2kHz, fs = 8kHz. 2, using LMS algorithm, the input to the equalizer training sequence plus interference equalizer order is 21 bands, step factor β = 0.01. 3, the preparation of the floating-point LMS algorithm in Matlab, draw the output waveform equalizer, and with the training sequence comparison.)

利用MATLAB负折射率材料 导纳矩阵法(Negative refractive index materials using MATLAB admittance matrix)

决策树算法的matlab实现，主要适用的是id3 算法思想(Decision Tree Algorithm to achieve the matlab main id3 algorithm is applicable to thinking)

用MATLAB写的图像处理，包括绘制直方图，灰度拉伸，图像均衡化及频域平滑滤波代码，简洁实用，注释清晰(Written using MATLAB image processing, including the plot histogram, gray stretch, image equalization and frequency domain filtering code, simple and practical, clear notes)

实现加权最小二乘拟合，经典的系统辨识方法，很管用(Achieve a weighted least-squares fitting, classical system identification methods, it is useful)

MATLAB不提供现成指数拟合函数，一方面由于但可以轻松通过多项式拟合转化而来，但是使用上还是不如有一个函数方便，所以特写这样一样简单实用的函数(MATLAB does not provide ready-exponential fit function, by hand because it can be easily transformed a polynomial fit, but still not as good as there is easy to use a function, it is as simple close-up of such useful functions)
