平均滤波，对声音进行处理从而起到降低噪声作用(Average filter, which serve to reduce noise sound processing)

说明：  BP神经网络分类程序 学习分类方法 多个程序都可以运行 数据处理(BP neural network classification program learning classification method multiple programs can run data processing)

这是一个基本的PCA方法实现人脸图像压缩与重建，可以非常快捷的将一些无法辨别的人脸图像进行快速的拼接。(This is a basic PCA method to achieve image compression and reconstruction of the face, can be very quick to identify the human face that can not be quickly spliced images.)

能够将采集到的压力波数据TXT文件读出来，并显示波形(Able to read out the pressure wavedate collected and then display)

BEZIER_SURFACE_DISPLAY is a work in progress . I have managed to read the data in and display a crude image, in which each Bezier patch is represented by a flat rectangle. Obviously, I need to take the next step, which is to be able to sample the bicubic function and display a finer mesh of rectangles, in order to see the teapot in its glory!
