Currently, I am working with professor Oliver Cossairt and the Computational Photography Lab at Northwestern University for this project. We aim to perform three-dimensional skin surface reconstruction using the photometric stereo technique. Our purpose is to diagnose skin diseases, such as skin cancer, with low-cost set up. A python framework has been implemented to obtain the normal maps of hands using photometric stereo. Currently, we are working to fuse depth map and normal maps using the Nehab et al (2005) or the Zhange et al (2012) method to achieve a better overall shape for hands.
