| Abstract: | A robust digital watermarking scheme based on logistic chaotic sequences is proposed.The watermark is pre-processed by logistic chaotic sequences and spreading adaptively over the image wavelet domain.The experimental results demonstrate that the watermark is robust to general image processing techniques and provides considerable robustness and imperceptibility. |
