Webb15 juni 2016 · Shape from Shading (SFS) The idea of SFS is to reconstruct an object (Shape) from a 2D Image (Shading). There are a lot of ways to reconstruct a 3D Object from a 2D Image. Similar methods include Shape from Stereo, Shape from Contours, Shape from Silhouettes etc. WebbIn this paper, we propose a method to generate high-quality DTMs based on a synthesis of deep learning and Shape from Shading (SFS) with a Lunar Reconnaissance Orbiter Narrow Angle Camera (LROC NAC) image as well as a coarse-resolution DTM as input.
