完整实现Fisherface人脸识别，能够在AR、ORL、FERET等使用，采用彩色图像进行测试，实验效果好，有的能达到100 (This package implements a well-known FLD-based face recognition method, which is called Fisherface )

CIE色度图, CIE 1931 RGB, CIE 1931 XYZ, CIE 1931 xyY(CIE chromaticity diagram, CIE 1931 RGB, CIE 1931 XYZ, CIE 1931 xyY)

实现图像文件（如bmp等）的读取、显示、真彩图转换成灰度图、灰度图转化为二值图及绘制图像直方图功能。(Achieve an image file (such as bmp, etc.) to read, display, true color conversion to grayscale, converted to grayscale and binary image histogram function to draw the image.)

这是一种很强的人脸检测程序，你可以试试，但我也不知是用什么方法。(This is a very strong face detection process, you can try, but I do not know in what ways.)

sift算法的核心，siftWin32.exe的源程序，可执行，可导入Matlab(The core of the SIFT algorithm, the source of siftWin32.exe, executable, can be imported to Matlab)

图像预处理，包括灰度化、图像去噪、灰度变换、阈值分割、边缘检测，形态学处理(image preprocessing)

说明：  基于matlab的加窗傅里叶，使用了hanning窗(Matlab-based windowed Fourier, using the hanning window)

说明：  matlab图像处理用于目标分割，分割后的图像在用形态学滤波处理(matlab image processing for object segmentation, image segmentation using morphological filtering deal)

对流层与电离层中电波传播的相关问题研究,很好的文章(Troposphere and ionosphere wave propagation issues related to research)

说明：  本代码总结了信息熵、条件信息熵、PSNR、SSIM等图像评价指标(This code summarizes information entropy, conditional information entropy, PSNR, SSIM and other image evaluation indexes)
