其中imagelist.txt和train.txt的格式如下注释所示

widerface的官网给出了其数据集的mat格式的标签，因此一个读取其标签，将人脸扣取出的程序就迫在眉睫。本文的这个程序是一个很普通的程序，但是这个程序经过了验证，处理结果的正确性完全有保证。你可以花1个小时写一个这样的程序，但是你需要花3个小时进行验证和测试。这也就是本程序的意义所在。

 

本程序实现的功能：

1，读取所有图像，并将人脸图像保存到当前目录的filesave目录下

2，将新生成的图像保存到imagelist.txt中

3，将原始图像保存到train.txt中

4，对原始mat中的不在图像里面的人脸，进行了四舍五入和相应的处理

5，原始mat的人脸是亚像素的，进行了像素级别的处理

其中imagelist.txt和train.txt的格式如下注释所示。

 

% train.txt数据格式event_list\file_list\numx y w h

% 例如.\0--Parade\0_Parade_marchingband_1_849.jpg1 449 330 121 148

% imagelist.txt数据格式event_list_file_list_num.jpg

% 例如0--Parade_0_Parade_marchingband_1_849_1.jpg
