Three-Dimensional Reconstruction from Single Image Base on Combination of CNN and Multi-Spectral Photometric Stereo
Multi-spectral photometric stereo can recover pixel-wise surface normal from a single RGB image.The difficulty lies in that the intensity in each channel is the tangle of illumination, albedo and camera response; thus, an 6 Piece Outdoor Sectional initial estimate of the normal is required in optimization-based solutions.In this paper, we propose t
