An adaptive image watermarking algorithm based on neural-networks
Mei Shi-chun · Journal of China Institute of Communications · 2002
In this paper, the artificial neural network (ANN) is used to model human visual system (HVS) and an ANN-based image-adaptive method for deciding watermarking strength for image DCT coefficients is presented. The experimental results show that the method can increase the watermarking strength so that the robustness of digital watermark is enhanced and that the method has very good adaptability.
