A High-capacity Image Watermarking Scheme Based on Blind Source Separation
Yunhua Li · Journal of Nantong University · 2008
In this paper,a high-capacity image watermarking algorithm based on Blind Source Separation is proposed. In order to increase the capacity of watermarking,the corresponding sequences of watermarking pixels are added into the wavelet coefficients respectively.And the maximum strength of watermarking is limited according to Just Noticeable Difference of visual in order to assure the watermarking invisibility.By using the Blind Source Separation based on Independent Component Analysis,the watermarking is separated with the image data and obtained regardless of the method of watermarking embedment and watermarking strength.The efficiency of the algorithm is confirmed by the experimental test.
