Abstract

This paper describes an algorithm to watermark appearance attributes, as well as shape of mesh. Appearance attributes are potential watermarking primitives and watermarking approach for them can be generalized from that for the shape. The major challenge of generalization is that the watermarking for appearance attributes has more constraints. Our paper focuses on this challenge. Especially for normal vector, we embed watermark by modifying its orientation, not magnitude. Results show our scheme effectively improves the capacity and enhances the robustness of mesh watermarking.
