WebPhotometric stereo is a form of structured lighting that increases the information available from surface reflectance variations. Basically, instead of taking a single monocular image of a scene illuminated from a single source, several images are taken, from the same vantage point, with the scene illuminated in turn by separate light sources. WebPhotometric stereo is a technique to estimate depth and surface orientation from images of the same view taken from different directions. Theoretically, only three directions are sufficient to obtain normals, but to minimize noises inherent in the process, more than minimum number is often required for realistic images. ...
