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: yahui.cvrs@gmail.com
- 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~）
