Uncalibrated Photometric Stereo by Stepwise Optimization Using Principal Components of Isotropic BRDFs

The uncalibrated photometric stereo problem for non-Lambertian surfaces is challenging because of the large number of unknowns and its ill-posed nature stemming from unknown reflectance functions. We propose a model that represents various isotropic reflectance functions by using the principal comp…
