Gabor filter with 2 files, creategabor is the function agreeing with the gabor function, gabor is an sample for implementing and visualizing the gabor filter by 5*8 images

这是一个马乐土科夫-GM（1，1）的程序代码，一般用于预测，对于短期预测非常有效(This is a horse paradise Cove-GM (1,1) of the code, generally used for prediction, is very effective for short-term forecast)

三发一收的STBC误码率仿真，QPSK，瑞利衰弱信道，图很好(I collected three STBC BER simulation)

sift flow, a new method for decribing the images, it could be applied for many applications

声源波达方向估计，可以画出声源的方位二维图，(Sound source direction of arrival estimation, you can draw out loud the source of two-dimensional map of the azimuth,)

MATLAB source code. You can find useful address here.

the code is based on lsb matching revisited technique the new technique available to the user for steganography. that provide high accuracy

说明：  文件传输限制分多次上传，其他文件可以查看我的上传资料 本实验使用matlab神经网络工具箱搭建CNN网络实现手写字识别，里面附数据集和训练好的网络，准确率可达99%。 1.打开matlab2018 2.将路径设置为当前文件所在路径 3.直接运行test7_run.m即可得到网络在测试集里的准确率以及分类错误的样本。 test7_cnn_hwr.m：训练的程序 test7_run.m：测试测试集的代码，直接读取存储在net_trained.mat训练好的网络， 对测试样本进行分类，统计准确率。(In this experiment, we use matlab neural network toolbox to build CNN network to realize handwritten word recognition, which is attached with data set and trained network, with an accuracy of 99%.)

说明：  自己写的一个计算空间时频分布的程序，可知指定Cohen类分布类型WVD，CWD，PWVD，SPWVD，BJD(himself in a room when calculating the frequency distribution procedures, we can see Cohen category designated distribution type WVD, CWD, Wigner, SPWVD, BJD etc.)

Matlab实现通过优化多项式实现矩阵逼近源代码.附件中的代码通过多项式优化实现矩阵逼近算法。(Matlab achieve by optimizing polynomial matrix approximation of the source code and the code contained in the annex to achieve matrix approximation by polynomial optimization algorithm.)
