Automatic Illumination of Flat-Colored Drawings by 3D Augmentation of 2D Silhouettes

Abstract

Flat-colored drawing [1] (b) Estimated 3D elevation map (c) Estimated normal map (d) Two examples of automatic illumination rendering Fig. 1: Our method allows to automatically illuminate a flat-colored drawing (a), by estimating a plausible 3D elevation map from its silhouette (b), as well as a normal map (c). A Phong illumination model is then applied, able to generate different kinds of rendering (d).
