segmenting image processing using lazy snaping

实现以下功能：装载信号；完成信号的单尺度一维离散小波分解；从系数中重构低频部分和高频部分；显示高频和低频部分；由小波逆变换恢复信号；多层一维分解；提取系数的低频和高频部分；重构第3层的低频系数；重构第1、2、3、4、5层的高频信号；重构原始信号并显示(Achieve the following functions: load signal complete signal single-scale one-dimensional discrete wavelet decomposition reconstructed from the coefficients in the low frequency and high frequency display high-frequency and low frequency restored by the inverse wavelet transform signal multi-layer one-dimensional decomposition extraction coefficient of low frequency and high frequency reconstruction of 3-layer low-frequency coefficients reconstruction of the first layer of high-frequency signal 1,2,3,4,5 reconstruct the original signal and display)

利用fft2对图像傅里叶变换，在用lpfilter生成高斯低通滤波器，进行过滤再进行反变换最后显示(Use fft2 the image Fourier transform, in with lpfilter generate Gaussian low-pass filter for filtering the inverse transform last displayed)

通过MATLAB编程，利用Logistics映射生成随机数(By MATLAB programming, using Logistic map to generate random numbers)

说明：  在神经网络中用迭代法对人脸图像进行压缩及恢复(Iteration in the neural network human face using image compression and restoration)

现代优化源程序，十分有用，包括现代优化算法的实例讲解和源程序(Modern optimization of the source program, very useful)

关于永磁电机的无速度传感器控制，是基于模型参考自适应(it s a mdl project based on matlab.)
