Shape from self-calibration and Fast Marching Method

Shape from self-calibration and Fast Marching Method
Shape-from-shading methods recover 3-D shape from intensity images. Often, Lambertian reflectance is assumed. The Lambertian assumption is attractive because it simplifies the analysis. Alternatively, non-Lambertian reflectance, including specularity, is accommodated in methods that measure reflectance empirically either using a separate calibration object or the target object itself, in self-calibration. Here, a new Fast Marching Method (FMM) is described to recover 3-D shape. It assumes a single, directional light source aligned with the viewing direction. Non-Lambertian reflectance is handled via self-calibration based on controlled rotation of the target object. Experiments using both synthetic and real data are demonstrated.
