1、文件说明:
"wider_face_split.zip" 文件包含三个子文件:
wider_face_train.mat, wider_face_val.mat, andwider_face_test.mat.
其中,每个子文件中元胞数组:
The 'event_list'包含61个种类的文件夹名
The 'face_bbx_list' 包含每个种类中图片中人脸的标注矩形框
The 'file_list' 包含每个种类中图片名
标注的矩形框的格式如下:
参考地址:http://mmlab.ie.cuhk.edu.hk/projects/WIDERFace/support/example/README.txt
2、 要求
导出数据为如下格式
格式:event_list\file_list\face_bbx_list
注:
event_list、file_list、face_bbx_list三个元胞数组里面的内容是一一对应的,切记要一一对应。
