| Abstract: | A fast algorithm of noncommutative wavelet transformation is given, and an algorithm for digital image watermarking based on the theory of noncommutative wavelet is presented, in which watermark is adaptively embedded according to error. The robustness and the imperceptibility are both considered and blind extracting is achieved. The examples demonstrate that the watermarking algorithm is robust against general image processing and geometric distortions, and has strong capability against cutting. |
| Keywords: | computer application information security noncommutative wavelet digital watermarking |
