A Novel Watermark Scheme Based on Image Independent Feature
Jiande Sun · Journal of Circuits and Systems · 2003
Recently, Independent Component Analysis (ICA) was used to extract image features. At the same time, the ICA-based watermarking techniques appeared. In this paper, a novel watermarking method is proposed, in which DCT is used to do in-depth processing after ICA to remove the correlation between the elements of the independent components, and then the watermark is embedded into the coefficients. Further more, estimation of the attack is performed and it improves the robustness.
