压缩包中是几款LDA人脸特征识别的程序，和文章，一共是4个程序吧，有MATLAB的还有C++的(Compressed packet is LDA several facial feature recognition procedures, and articles, a total of four procedures you have MATLAB are C++ the)

说明：  滤波的常用方法,数字图像处理的常用滤波算法，试过，可以用！(Common method of filtering, digital filtering algorithm commonly used in image processing, tried, you can use!)

matlab的界面编程的资料，详细的步骤可供初学者参考(the matlab interface programming, detailed step reference for beginners)

使用matlab的小波分解和重建函数对24位的ADC采样数据进行小波变换和去噪，去噪使用阈值算法，阈值的选取具体使用了6种方法进行对比，对于不同信号其效果是不同的！把去噪后的信号和原始信号放在一个图中，使用不同颜色的曲线进行对比，效果可以很直观的表现。(Using matlab wavelet decomposition and reconstruction of the function for 24-bit ADC sampling data wavelet transform and denoising, denoising using the threshold algorithm, the threshold selecting specific methods used six kinds of contrast, the effect for different signals is different The! After the denoising signal and the original signal on a map using different colors to compare curves, the effect can be very intuitive performance.)

it is a very simple and helpful document and source code for image compression

说明：  Matlab是科学计算与仿真中常用的工具软件，本文阐述Matlab编程中需要注意的问题！(Matlab is commonly used in scientific computing and simulation software tool, this paper, Matlab programming issues that need attention!)
