Abstract :
A kind of new image watermarking scheme is proposed in this paper, which is based on Fast Independent Component Analysis to extract the watermarking. In this scheme, a binary image is embedded into the approach sub-image in Discrete Wavelet Transform domain. When extracting the watermarking, a Fast ICA method is used. The experiment results show that the scheme has strong robustness against many attacks.
