Shape from shading

Classical “Shape from shading” theories assume that surfaces are perfectly
Lambertian (thus the radiance at the eye is perfectly proportional with irradiance) and
that each part of the surface is illuminated by the same source. Then the radiance received by the eye depends only upon the angle between the local surface normal and the net flux vector. Shape from shading is the problem of recovering the shape of a surface from this intensity variation is known as shape from shading. I prepared this presentation about “Shape from shading” and I decided to share it here as well 🙂 I love to learn new things and then teach (present) them to other people.
