1. A method of modeling a two dimensional representation of a three dimensional scene having at least one object, comprising: modeling the two dimensional representation of the at least one object as a reliable lattice with respect to a classification of nodes according to a classification criterion, having a lattice reliability defined by both a set of node classification reliabilities and a set of link reliabilities between nodes having linked classifications, for each of a plurality of node classifications and link classifications, respectively; maximizing the lattice reliability of the reliable lattice by altering the classification of nodes using an automated system; performing region-level verification of the reliable lattice having maximized reliability based on morphological constraints using the automated system; and outputting object information for the at least one solid object, from the automated system, based on the verified reliable lattice.
