A Method for Digital Watermarking Using ICA
Shen Min-fenrsity · Computer Engineering and Science · 2004
Digital watermarking technology develops quickly during the recent few years and is widely applied to protecting the copyright of digital images. A digital watermark is the information that is imperceptibly and robustly embedded in the host data such that it cannot be removed. This paper proposes a method based on the independent component analysis (ICA) of digital image watermarking. Experimental results indicate that the presented approach is remarkably effective in detecting and extracting digital image watermarks, and features robustness.
