A Method for Digital Watermarking Based on ICA
Guo Xiu-feng · Journal of Henan Normal University · 2009
The paper proposes a new method of extracting digital watermarking from using independent component analysis.There are two images which are embedded watermarking by mixing the original image and digital watermarking image in the space domain.The watermarking image is invisible under the control of the mixed matrix.Guaranteed high quality images with embedded watermarking.The mixed images are separated as blind source without needing any information of the original images and mixed matrix in the entire extraction process.The simulation experiments indicate that the project achieved a good unification of the robustness and invisibility of the watermarking.
