Abstract

In this paper we describe a novel framework for watermarking 3-D objects via contour information. Instead of classical existing watermarking technologies dealing with 3-D objects that operate on the object itself to insert and extract the mark (3-D/3-D approach), the goal of our work is to retrieve information originally hidden in the apparent contour of the object from resulting 2D images or videos having used the 3D synthetic object (3-D/2-D approach). In this paper we also propose an extension of 2-D polygonal line watermarking algorithm to 3-D silhouette.
