一个关于数据降维的工具包，外国牛人编写，囊括了各种降维方法，是一个很好的工具！(A tool for data reduction package, foreign cattle were written, include a variety of dimension reduction method is a good tool!)

主成分分析程序,应用于图像特征提取，数据降维等方面 (the code of PCA)

说明：  小波阈值去噪。对灰度图像和二值图像进行滤波。(Wavelet thresholding filter . Denoiseing for the gray image and binary image .)

故障分为很多种，该程序是利用小波包把故障特征提取出来，用于判断接下来出现的情况是把一种故障(The fault is divided into many, the program is using wavelet packet to extract the fault features out, used to judge the next case to a fault)

图像的高斯与拉普拉斯金字塔分解，两种方法都有(Image gaussian and Laplacian pyramid decomposition, there has two kinds of method)

GFT图片格式转换源码，程序根据腾讯皮肤GFT图片的格式，进行字节集的操作实现GFT图片的转换。(GFT image format conversion source code , the program according to Tencent skin GFT picture format operation byte set to achieve GFT image conversion.)

图像处理中经常需要检测圆形状的物体，该程序用霍夫变换可以检测圆的圆心和半径。(Image processing often requires detection of a round-shaped objects, the program can detect the use of Hough transform and radius of the center circle.)

说明：  微表情识别代码，可以识别高兴，悲伤，痛苦，愤怒等微表情。(Micro expression recognition code)

《数字图像处理（第三版）》课后习题答案，作者冈萨雷斯(Answers to Exercises after Class of Digital Image Processing (Third Edition),author Gonzalez)

说明：  使用GDAL的c#版本读取栅格图 gdal文件已经编译完成(Use C version of Dgal to read raster)
