What Is the Range of Surface Reconstructions from a Gradient Field?

Abstract. We propose a generalized equation to represent a continuum of surface reconstruction solutions of a given non-integrable gradient field. We show that common approaches such as Poisson solver and Frankot-Chellappa algorithm are special cases of this generalized equation. For a N ? N pixel grid, the subspace of all integrable gradient fields is of dimension N2
