This repository is a first try at Photometric Stereo. It mainly targets researchers needing an implementation of the early papers in photometric stereo, mainly  and . Note that these formulations are now considered obsolete, you should look at newer papers for an up-to-date and efficient formulation. For state-of-the-art Photometric Stereo methods, please look at our publications for references:
