实现多光谱图像的物质分类和显示，并进行面积统计。可以设置类数和采样数，采样时，用鼠标选取采样点，每类采样点选完，需要输入类名-This program can realize the classification and demonstration of multispectral images,and the area statistics of the class. In the program, you can set the number of class and sampling freely, and choose some images from many multispectral images. when sampling, you need to use the mouse to choose the sampling point and input the class name if the number of multispectral images choosed and sampling is big, you should consider the problem of memory, sometimes, there is the problem



of　 out of memory . The RAR file includes the main classification program.
