基于matlab的实时人脸表情识别程序源代码

说明：  外国人开发的电磁时域有限差分方法工具包 Electromagnetic Finite-Difference Time-Domain (EmFDTD) is a basic two-dimensional FDTD code developed at the School of Electrical Engineering, Sharif University of Technology. This code has been written based on the standard Yee s FDTD algorithm. Applications include propagation, scattering, and diffraction of electromagnetic waves in homogeneous and non-homogeneous isotropic media for in-plane propagating waves. Negative permittivites or permeabilities as well as dispersion is not included. Zero, Periodic, and Perfectly Matched Layer boundary conditions may be selectively applied to the solution domain. The program is best suited for study of propagation and diffraction of electromagnetic waves in Photonic Crystal structures. EmFDTD is written in MATLAB language and has been tested under MATLAB 5.0 and higher versions.(Foreigners developed electromagnetic FDTD method Toolkit Electromagnetic Finite-Difference Time-Domain (EmFDTD) is a basic two-dimensional FDTD code developed at the School of Electrical Engineering, Sharif University of Technology.

说明：  这个程序根据训练好的网络文件ANN.mat预测新的数据文件，得到均方误差，并画出预测数据和原数据的对比图。此程序运用到了很多Matlab编程中常用到的表达方式，还有一些神经网络编程的基本概念的表达，如归一化的表达。希望能对大家有所帮助(This program the trained network file ANN.mat predict new data file, get the mean square error, and forecast data and the original data to draw the comparison chart. This procedure applied to a lot of Matlab programming to the expression commonly used, there are some basic concepts of neural network programming expression, as normalized expression. Hope you can help)

模拟噪声的程序，可以根据需要改写，主要功能是实现噪声模型 (Additive Noise Channel/Additive Guassian Noise Channel is the simplest of all channels. File usage details: op_channel = additivenoise(input_signal) mathematical Model: s(t) input signal to channel (=sig_ip) n(t)additive random noise process added by channel (=noise_mat) a(t) attenutation factor , here it is taken as random(=att_fact) out put signal r(t) = a .* s(t)+ n(t) an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal )
