Analytical Solution of Shape from Shading Problem

A new geometrical approach in solving the shape from shading problem of Lambertian model is discussed. It is shown that this problem is bound by two local constraints through the global and local geometrical analysis and through the direct geometrical interpretation of the problem. The analytical solutions, which are C1 continuous and which have two degrees of freedom due to the non-linear property of the problem, are derived. This proves existence and non-uniqueness of the solution.
