A Robust Blind Water Marking for 3D Meshes Using Distribution of Scale Coefficients in Irregular Wavelet Analysis

We propose a new method for watermarking of 3D surface mesh. After irregular wavelet analysis, the watermark is embedded in the scale coefficients. We modify the mean of the distribution of the vertex norm of the approximation mesh in order to obtain blind scheme which does not require the original mesh for detection. Experimental results show the effectiveness of the proposed algorithm both in terms of invisibility and robustness against simplification and progressive lossy compression
