BP神经网络识别手写字符验证码，包括10721张字母、数字样本(BP neural network handwritten character recognition codes, including 10,721 letters, numbers, samples)

这个程序在MATLAB环境下实现二值图像的水印注入及水印提取(The program aim to achieve the watermark into the binary image and the watermark extraction under MATLAB environment)

基于mathematics开发的条纹质心搜索及处理程序(Fringe centroid search and processing programs based on Mathematics)

绘制gabor滤波器的时域和空域图形，具有一定的参考价值。(Draw the time and space domain graphics .And it has a certain reference value.)

x0 = ones(2,2) Make a starting guess at the solution options = optimset( Display , off ) Turn off Display [x,Fval,exitflag] = fsolve(@myfun,x0,options) The solution is x = -0.1291 0.8602 1.2903 1.1612 Fval = 1.0e-009 * -0.1619 0.0776 0.1161 -0.0469 exitflag = 1 and the residual is close to zero. sum(sum(Fval.*Fval)) ans = 4.7915e-020

1.同时对多个光谱数据进行一阶导数计算，并保存在元胞数组中。2.对光谱数据进行取均值，每三个列为一组。(At the same time, the first derivative of multi-spectral data is calculated and stored in the cell array.The spectral data are averaged and divided into three groups.)

说明：  4. 试说明卷积编解码的工作原理。请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4 Explain the working principle of convolutional encoding and decoding. Please use the Simulink simulation convolutional coding and Viterbi decoding method used to decode, in which the encoding, decoding all write your own code (S-Function mode), instead of calling the Simulink existing encoding and decoding functions. In additive white Gaussian noise channel, signal to noise ratio and bit error rate to draw the curve.)
