ON DIGITAL MODEL OF WATERMARKING BASED ON INDEPENDENT COMPONENT ANALYSIS
Pla Information · Computer Applications and Software · 2009
A method of digital model watermarking based on Independent Component Analysis(ICA) is proposed in this paper.When embedding watermarking,the original model is decomposed by first-level discrete wavelet transform,the obtained approximation coefficient vector is embedded with watermarking by mixing randomly,and then the inverse transform is performed to reconstruct a model with embedded watermarking.When extracting watermarking,the model is decomposed by first-level discrete wavelet transform,and the watermarking is extracted by ICA based on kurtosis maximization.Emulated experiment results show that this method is robust and feasible.This method can protect the copyright of digital model effectively.
