Lambertian Reflectance and Linear Subspaces. Lighting gt infinite DOFs. Explains previous empirical results.
Accuracy depends on lighting. For point source 9D space captures Albedo makes some pixels more important. Worst case approximation arbitrarily bad.
Average case approximation should be good. With no shadows, illn with B lX,lY,lZ.

First harmonic, no DC Koenderink van Doorn heuristically suggest using l too. Pose automatically computed using manually selected features Blicher and Roy. Best lighting found for each model best fitting model wins.
Ongoing work Most errors seem due to pose problems. With better poses, results seem near Useful for recognition with 3D model. Also tells us how to generalize from images.
