在一些图像处理或者数据处理时，需要给计算返回的数据指定一个存储路径，如果直接以被处理的文件所在路径下，并以其名命名自动生成一个文件夹，挺方便的，做法如下;

• CreateSubfolder.h

/* create subfolder for results saving.   - Email:  [e-mail]   - Address: Computer Vision and Remote Sensing(CVRS) Lab, Wuhan University. */#ifndef CREATE_SUBFOLDER_H#define CREATE_SUBFOLDER_H#pragma once#include <direct.h>#include <stdlib.h>  #include <stdio.h> #include <string>using namespace std;class CreateSubfolder{public:    CreateSubfolder(){}    ~CreateSubfolder(){}public:    /*       Create a subfolder according to the full-path of the input filepathh        - filepath: full path, input        - subfolder: created folder, output        - filename: name of the input file, output    */    static void creatSubfolderViaFname(         char* filepath, char* subfolder, char* filename );};#endif // CREATE_SUBFOLDER_H

• CreateSubfolder.cpp

#include "CreateSubfolder.h"void CreateSubfolder::creatSubfolderViaFname(     char* filepath, char* subfolder, char* filename ){    char drive[_MAX_DRIVE];    char dir[_MAX_DIR];    char fname[_MAX_FNAME];    char ext[_MAX_EXT];    _splitpath(filepath, drive, dir, fname, ext);    char* subDir = new char[_MAX_DIR];    sprintf(subDir, "%s\%s\\", dir, fname);    sprintf(subfolder, "%s\%s", drive, subDir);    _mkdir(subfolder);    sprintf(filename, "%s", fname);    delete[] subDir;}

比如，下面的例子，对一张图片抠出每个单独的图形，并存在该文件夹下：

运行完就是这效果：

（图像处理的代码很简单，就不公布啦~）
