Wei Zhang, Weihua Zhu, Yunqing Fu · 2005
As a potent method of copyright evidence for digital media, digital watermarking has become an important issue, especially in recent years. An adaptive digital watermarking approach is presented in this paper. Based on fuzzy c-means clustering technique and human visual system model, the proposed approach can adaptively select the strength value of watermark. Compared with other meams, the embedded watermark is more imperceptible and robust. At the same time, the anti-attack ability of embedded watermark is stronger in frequency domain than in spatial domain. In the end, experimental results are given to verify that the approach is applicable and piractical.
