Abstract
Fast intrinsic images techniques are described. In one or more implementations, a combination of local constraints on shading and reflectance and non-local constraints on reflectance are applied to an image to generate a linear system of equations. The linear system of equations can be solved to generate a reflectance intrinsic image and a shading intrinsic image for the image. In one or more implementations, a multi-scale parallelized iterative solver is used to solve the linear system of equations to generate the reflectance intrinsic image and the shading intrinsic image.
