This paper proposes a new approach to recover the 3-D shape of a color textured object via self-calibration. Many empirical photometric approaches use a calibration object. Multiple light sources allow one to recover both the color refectance and the shape of a target object. Here, a new Fast Marching Method (FMM) algorithm is proposed to recover 3-D shape for the case of a single parallel light source aligned with the viewing direction. Color reflectance factors based on a dichromatic reflectance model are estimated using clustering. Subsequently, a Lambertian shaded image is generated using a conversion table. Experiments with both synthetic and real data are demonstrated.
