Data Structure

FreeMan consists of 2 subsets corresponding to 30FPS & 60FPS, respectively. Each subset data includes RGB videos, camera parameters, 2D & 3D human keypoints, SMPL parameters, bounding boxes. File structure is shown as below. Data are grouped into different folders by data types.
yyyymmdd_xxxxxxxx_subjNN is the unique name for each session. yyyymmdd refer to capture date, xxxxxxxx refer to uuid of the session, NN refer to subject id. Details can be found in Documentations.
