C++图像批处理：读取文件夹中全部图像的方法

string file_path = "H:\\image data\\";

string search_path = file_path + "*.jpg";

vector<string> file_list;

if (!get_filelist_from_dir(search_path, file_list))

cout << "open file error!" << endl;

for (int i = 0; i < file_list.size(); i++)

{

string image_path = file_path + file_list[i];

Mat image = imread(image_path);

/*处理*/

}

get_filelist_from_dir()函数的定义如下：

#include <io.h>

bool get_filelist_from_dir(string path, vector<string>& files)

{

long   hFile   =   0;

struct _finddata_t fileinfo;

files.clear();

if((hFile = _findfirst(path.c_str(), &fileinfo)) !=  -1)

{

do

{

if(!(fileinfo.attrib &  _A_SUBDIR))

files.push_back(fileinfo.name);

}while(_findnext(hFile, &fileinfo)  == 0);

_findclose(hFile);

return true;

}

else

return false;

}
