Image Recognition and classification

说明：  小波软阈值simulink模型,对带噪语音信号进行小波分解，得到高低频系数，然后对高低频系数进行阈值处理，然后就行重构得到去噪语音信号(the simulink model of yuzhi)

说明：  跳频扩频传输系统仿真模型 文件名：ch7example28.mdl(Frequency-hopping spread-spectrum transmission system simulation model of the file name: ch7example28.mdl)

指纹识别预处理 matlab程序 包括 指纹增强 二值化 细化 等步骤(Fingerprint preprocessing including fingerprint enhancement matlab program binary refinement step, etc )

编写一个可以从一幅图像中提取一幅矩形子图像的函数。(Write an image can be extracted from an image of a rectangular sub-functions.)

matlab中矩阵的操作，一些简单的操作，记不住的时候，可以看看( matrix operations in matlab)

这是一个雷达恒虚警matlab仿真程序，效果比较好(This is a radar CFAR matlab simulation program, the effect is better)

Matlab 仿真uwb信道的功率谱密度(Matlab simulation of UWB channel power spectral density)

The following fuzzy modeling exercises run in the MATLAB environment. The interaction required by the user is guided by instructions and editable fields menus. The user can change various parameters of a system, and execute modeling commands to verify the resulting system. In some exercises, it is also possible to manually edit the fuzzy system initially generated with the parameters given by the user, in order to enhance and fine tune the performance of the model.
