3D shape reconstruction is a classical problem in the field of computer vision. Shape from shading (SFS) is one approach to obtain the 3D shape from a single shading image. And Lambertian surfaces are an important assumption in traditional SFS methods. However, Lambertian reflectance model used to express the reflectance property of diffuse reflection is proved to be inaccurate. In this paper, we...
In order to reconstruct a surface which has specular reflection from the grayscale information contained in a single two-dimensional (2D) image, a specular shape from shading (SFS) using the fast marching method is presented. Under assumptions that the camera performs an orthographic projection whose direction is equal to the direction of the light source and that the Phong model is used to depict...
