This is a MFC command handler function for a button click event in a view class. It checks if a file is open and if there are any selected areas before proceeding with the classification process. Then, it creates a new object of the CSupervised class and allocates memory for storing the data. It opens the input file and reads the data into the allocated memory. Finally, it calls the MinimumDistance function of the CSupervised class to perform the classification and closes the input file. After the classification, it frees the allocated memory
