Abstract : This paper deals with the complexity of the decomposition of a digital surface into digital plane segments DPS for short. We prove that the decision problem does there exist a decomposition with less than k DPS ? is NP-complete, and thus that the optimisation problem finding the minimal number of DPS is NP-hard. The proof is based on a polynomial reduction of any instance of the well-known 3-SAT problem to an instance of the digital surface decomposition problem. A geometric model for the 3-SAT problem is proposed.
