A novel digital watermarking scheme based on ICA
Chunxing Wang, Guanlan Liu · 2011
In this paper, a novel digital image watermark scheme based on ICA (independent component analysis) is proposed. The DWT (discrete wavelet transform) is performed to each independent feature component of the original image, and the scrambling watermark is embedded into the medium frequency component. The experimental results indicate that the watermark has a good performance to survive some common attacks as well as some fierce attacks.
