Applying spread transform dither modulation for 3D-mesh watermarking by using perceptual models

Primary tabs

Darazi, Rony [UCL] Hu, R. Macq, Benoît [UCL]

A 3D-mesh watermarking method is proposed in this paper. The watermarking occurs in the spherical coordinates system, where only the vertex norm of each point is modified. The embedding method is based on Spread Transform Dither Modulation (STDM). A perceptual model based on the curvature and the roughness of the 3D mesh is defined and is used to modulate the STDM method. Our results show that the proposed method has high tolerance to noise and is robust against mesh smoothing.
