Shape-from-shading (SFS) is to reconstruct three-dimensional (3D) shape from a single gray image, which is an important problem in computer vision. We propose a novel SFS method based on hybrid reflection model wh...
This paper translates the recognifion of curvatare radius in robot moving in bent pipe into an issue of shape-from-shading, and introduces genetic algorithms into the optimizaton process to improve the efficiency of o...
