| Abstract: | Due to the unpredictability property of chaotic sequence,chaos theory can be used in the process of creating the digital watermarking.A robust digital watermarking scheme based on Logistic chaotic sequences is proposed.The watermark is preprocessed by Logistic chaotic sequences and spread adaptive over the image wavelet domain.The experimental results demonstrate that the watermark is robust to general image processing techniques and geometric distortions. |
