Color Image Adaptive Watermarking Algorithm in DCT Domain Based on Chaotic Scrambling
Yong Yu · Journal of Sichuan University · 2004
Based on the good property of chaotic sequences as scrambled sequences, the authors propose a scrambled network of chaotic image with chaotic sequences' order-statistic, and then adaptively embed chaotic scrambled image in 2-DCT domain with mankind's sensitive difference in monochromatic images. Experiment results show that the proposed algorithm can trade off the conflict of transparency and robustness of invisible watermarking well and the generated watermarking withstand under common attacks very well
