matlab光学仿真，模拟光线的反射、折射；非常强大的光学仿真软件。(Matlab optical simulation,Simulate the reflection and refraction of light;;very powerful optical simulation software.)

介绍matlab下求解偏微分方程的函数和用法(Introduction matlab function for solving partial differential equations and usage)

说明：  主要颜色谱 计算主要的颜色来舍弃其他的颜色，用少数的颜色个数代替大多数进行聚类(Main color spectrum calculation primary colors to abandon other colors)

数字图像处理用到的标准测试图像，很多图片。(IMP test images。)

用于求取灰度图光斑的中心，可以用于寻找光斑图像的中心，如激光光斑，(Used to strike a grayscale facula center spot can be used to find the center of the image, such as the laser spot,)

N-FINDR算法 端元提取 读取MNF降维后的影像数据 读取MNF降维后的影像数据( using N-FINDR end-member extraction)

说明：  image 数组 高速读写 不用指针(image array IO C#)

说明：  小波变换是图像的多尺度、多分辨率分解，它可以聚焦到图像的任意细节，被称为数学上的显微镜。近年来，随着小波理论及其应用的发展，已将小波多分辨率分解用于像素级图像融合。把两个正交偏振的图片融合(Wavelet transform is the multi-scale and multi-resolution decomposition of an image. It can focus on any detail of the image and is called the mathematical microscope.In recent years, with the development of wavelet theory and its applications, wavelet multi-resolution decomposition has been applied to pixel-level image fusion)

自己编写的图像腐蚀与膨胀matlab代码，经试验证明与matlab中自带的腐蚀和膨胀函数运行效果相同，可供初学图像处理的同学参考使用。(The image corrosion and expansion matlab code written by myself has been proved to be the same as the corrosion and expansion function of the matlab. It can be used by students who are ready for beginner image processing.)

利用误差扩散算法中的Floyd-Steinberg抖动算法来对图像进行二值化处理，从而方便图像调频加网输出(The use of error diffusion algorithm of Floyd-Steinberg dithering algorithm to image binarization treatment, thus facilitating image output FM Screening)
