The 3D Relightable Facial Expression (ICT-3DRFE) database enables experimentation in the fields of 
			both computer graphics and computer vision. The database contains 3D models for 23 subjects and 15 
			expressions, as well as photometric information that allow for photorealistic rendering. It is also 
			facial action units annotated, using FACS standards.
			
			The datasets were captured in the USC ICT Light Stage with the polarized spherical gradient illumination
			technique described in Rapid Acquisition of Specular 
			and Diffuse Normal Maps from Polarized Spherical Gradient Illumination, EGSR 2007.
