Recovering decorative patterns of ceramic objects from a monocular image using a genetic algorithm

Abstract

In order to develop a shape and decorative pattern database of old pottery and ceramics objects, it is necessary to obtain the surface pattern on the 3-dimensional shape of the object. This paper describes the recovery of the revolution surface from a monocular image of unknown camera parameters and the retrieval of the 2-dimensional pattern. The camera parameters are obtained by using a genetic algorithm (GA). After the revolution surfaces are reconstructed, these surfaces are developed into a 2-dimensional plane. We show that a scanner-digitized image of an old ceramic object can be analyzed by GA to reconstruct the revolution surface and to develop the 2-dimensional image on the 3-dimensional object.
