ABSTRACT:
A method, for practice on a computer, for interpreting two-dimensional images of three-dimensional scenes is disclosed. Descriptive labels are assigned to the vertex, edge and face elements of the image. A process of constraint satisfaction and propagation is carried out between image elements that are linked together with the effect of pruning away locally inconsistent labels at each element. The remaining labels assigned to the image elements are both locally and globally consistent.
