Application of ICA to the digital image watermarking
Minfen Shen, Jeffrey R. Huang, Patch J. Beadle · 2003
Digital watermark processing technology has developed very quickly during the recent few years, and been widely applied to protect the copyright of digital image, audio, video and multimedia production. In this paper, a method based on the independent component analysis (ICA) technique for detection and extraction of digital image watermark is proposed. With ICA techniques, it is ensured that a better-extracted watermark can be obtained. Several results of experiments indicate the proposed method is remarkably effective.
