A Numerical Method for Shape-From-Shading From A Single Image (opens in new tab)

A Numerical Method for Shape-From-Shading From A Single Image Strat, Thomas M. The shape of an object can be determined from the shading in a single image by solving a first-order, non-linear partial differential equation. The method of characteristics can be used to do this, but it suffers from a number of theoretical difficulties and implementation problems. This thesis presents an iterative relaxation algorithm for solving this equation on a grid of points. Here, repeated local computation...
