Shape-from-shading is a classic ill-posed technique for 3D-reconstruction, which suffers from the well-known concave/convex ambiguity. However, if may recover thin details of the 3D-shape. On the other hand, multi-view stereo is not satisfactory either: if the overall 3D-shape is reasonable, thin details are missing and artefacts appears in the textureless areas. We propose a simple yet effective strategy for combining the advantages of both techniques.
