A Variational Approach to Shape-from-shading Under Natural IlluminationMS57

We propose a novel variational approach to shape-from-shading. It is based on a modification version of the Horn and Brooks approach into an integrated, constrained variational model which simultaneously estimates both the depth map and its gradient. Numerical solution can be estimated by resorting to an ADMM algorithm. We show that this approach is straightforward to extend in order to handle non-directional, natural illumination, RGB images, or various regularizers.
