Most of progressive mesh (PM) transmission techniques, con-
sist in iteratively decimating the mesh, while storing the information
necessary to the process inversion. During the transmission or visual-
ization the 3D content can be duplicated and redistributed by a pirate.
Digital watermarking is considered as a good solution to this emerging
problem. This paper focus on introducing a novel robust and blind mesh
watermarking schema by converting the original triangle mesh into a
multi-resolution format, consisting of a coarse base mesh and a sequence
of re nement, the watermark bits are inserted through progressive mesh
level of details, and extracted at re nement stage without any need for
the original model. The watermark insertion is performed only on set of
marked vertices come out from Self Organization Maps (SOM) cluster-
ing neural network. These vertices are used as candidates for watermark
carriers that will hold watermark bits through progressive mesh transmis-
sion. The robustness of proposed techniques is evaluated experimentally
by simulating attacks such as mesh smoothing, noise addition and mesh
cropping.
