Improving the Detector Performance by Exploiting a Feedback Model

A new watermarking-embedding scheme is proposed to improve the detector performance. The embedder employs the media to control both the fidelity (using a visual model) and the detectability (using a feedback of the watermark detector). Media-content dependent watermark modulation can effectively resist copy attack and removal attack. Experimental results show that the proposed scheme has a distinguished achievement in the detectability.
