在数字图像处理中，运用MATLAB中的函数compare可以用来计算图像压缩前后的误差和直方图(In digital image processing using MATLAB functions compare the error and histogram can be used to calculate the image before and after compression)

matlab 画地图的 非常好用，有需要的可以拿过去！(very good！)

此代码为灰色预测GM（1,1）代码，其中包括了各个参数的计算及误差(This code is gray forecasting GM (1,1) code, including the calculation of the various parameters and error)

Gray threshold segmentation: Using Twin Peaks method a gray image gray-scale be dealt with separately.)

DTMF decoder in matlab

The goal of SPID is to provide the user with tools capable to simulate, preprocess, process and classify in vivo and ex vivo MRS signals. These tools are embedded in a matlab graphical user interface (GUI). (Pre)processing and classification methods can also be automatically run in a row using the matlab command line
