| Abstract(in English) | In traditional 3-D shape inference from shading, surface norm distribution is estimated by using a traditional constraint imposed on surface norm and image brightness. In this paper, we derive another new type of constraint imposed on surface norm and gradient of image brightness, and propose 3-D shape inference algorithm by using both the traditional constraint and the new type of constraint. We prove that the rate of convergence of the algorithm becomes faster by using the new type of constraint in additon to the traditional constraint. The usefulness of the new type of constraint is shown by numerical experiments. |
