OFDM_TFO

这个函数提供灰度拉伸功能，输入图像应当是灰度图像，但如果提供的不是灰度图像的话，函数会自动将图像转化为灰度形式。x1，x2，y1，y2应当使用双精度类型存储，图像矩阵可以使用任何MATLAB支持的类型存储。(This function provides a gray scale stretching function of the input image should be grayscale image, but if not provided, then gray image, the function will automatically be converted to grayscale image form. x1, x2, y1, y2 should use double precision storage, image matrix can store any type of MATLAB support.)

说明：  灰色模型预测是在数据不呈现一定规律下可以采取的一种建模和预测方法，其预测数据与原始数据存在一定的规律相似性(Grey model prediction is a kind of modeling and prediction method that can be adopted when the data does not show certain rules. There is certain regularity similarity between the prediction data and the original data)

彩色图像转灰度图像的三种算法，matlab实现(Color image to grayscale image of the three algorithms, matlab implementation)

C语言编写的直方图求法matlab程序，带详细解释和所需图片(histogram with C language )

非常好用的matlab相机标定。可以自动估算出内部和外部参数(matlab toolbox for dot pattern based camera calibration. It estimates the intrinsic and extrinsic parameters of the cameras. The 3D model can be also refined via optional bundle adjustment)

应用于衍射光学模拟，可以在物理光学教学中使学生能够获得感性认识，是非常重要的(Applied to diffraction optical simulation, can be in physical optics teaching so that the students can get perceptual knowledge, is very important )

说明：  改进的OMP算法，利用残差变化率作为迭代终止条件，提高了运算速度(The improved OMP algorithm uses the residual change rate as the iteration termination condition, which improves the operation speed)
