function WiderFace2VOC()

% The corresponding annotations are in the following format:
% Here, each face bounding boxe is denoted by:
% <x_left y_top width height>.

%% voc

%前面是图片名，中间是目标类别，最后是目标的包围框坐标（左上角和右下角坐标）。

因为只下到了training_1和training_3所以要从training中筛选出training_1和training_3，C++程序如下：

// UCCSProcessing.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include<opencv2/opencv.hpp>
#include<iostream>
#include<fstream>
#include<sstream>
#include<string>
using namespace std;
using namespace cv;


int _tmain(int argc, _TCHAR* argv[])
{
	ifstream InputFile("training.txt");
	ofstream OutputFile("training_results.txt");
	stringstream ss;
	string line,filename,filename_temp;
	int index, SUBJECT_ID;
	double x, y, w, h;
	getline(InputFile, line);
	Mat image;
	int i = 1;
	while (getline(InputFile, line))
	{
		ss.str("");
		ss.clear();
		ss << line;
		ss >> index >> filename >> SUBJECT_ID >> x >> y >> w >> h;
		filename_temp = "D:\\UCCS\\training_1_3\\" + filename;
		image = imread(filename_temp);
		if (image.data)
		{
			OutputFile << i << " " << filename << " " << x << " " << y << " " << w << " " << h << endl;
			i++;
		}
		
	}
	InputFile.close();
	OutputFile.close();
	return 0;
}

输入的training_1_3文件输入到WiderFace2VOC.m中
