opencv 遍历文件夹里面图像--实现

后来，我自己用VS2012+Opencv2.4.8实现了一下，只是没有显示图像。后来，稍微修改了一下，可以显示图像喽，这样就可以批处理指定目录文件夹里面的图像了。

1.head.h头文件

#ifndef _HEAD_H_
#define _HEAD_H_

//OpencvDirTraverse.cpp : Defines the entry point for the console application.
#define _CRT_SECURE_NO_DEPRECATE

#include <cstdio>
#include <vector>
#include <iostream>
#include <fstream>
#include <cstring>
#include <cstdlib>
#include <cmath>
#include <algorithm>

#include "opencv\cv.h"
#include "opencv2\core\core.hpp"
#include "opencv2\highgui\highgui.hpp"
#include "opencv2\imgproc\imgproc.hpp"
#include "opencv2\contrib\contrib.hpp"

using namespace std;
using namespace cv;

#endif // !_HEAD_H_

2.main.cpp源文件

#include "head.h"

int main(int argc, char * argv[])
{
  string dir_path = "D:/Test/";
  Directory dir;
  vector<string> fileNames = dir.GetListFiles(dir_path, "*.jpg", false);

  for(int i = 0; i < fileNames.size(); i++)
  {
    string fileName = fileNames[i];
    string fileFullName = dir_path + fileName;
    cout<<"file name:"<<fileName<<endl;
    cout<<"file paht:"<<fileFullName<<endl<<endl;

    //Image processing
    Mat pScr;
    pScr=imread(fileFullName,1); //以文件名命名窗口 
    imshow(fileName,pScr);
    waitKey(1000);


  }

  //system("pause");
  return EXIT_SUCCESS;
}
