In order to analyze the impact of the variation in both pose and lighting, we acquired data from 23 subjects under 6 illumination conditions. For each illumination condition, we asked the subject to face four different points inside the room. This generated rotations on the Y axis. For each rotation on Y, we also acquired 3 images with rotations on the Z axis (assuming that the Z axis goes from the back of the head to the nose, and that the Y axis is the vertical axis through the subject’s head). Thus, we acquired images under 6 illumination conditions, 4 Y rotations and 3 Z rotations per subject. In total, we have 72 pose/light variation per subject for 23 subject. Each capture consists of both 2D image captured using a Canon (TM) DSLR camera and a 3d mesh captured by 3dMD (TM) 2-pod optical 3D system.
