Foveated image watermarking [PDF]
Proceedings. International Conference on Image Processing, 2003 The spatial resolution of the human visual system (HVS) decreases rapidly away from the point of fixation (foveation point). By exploiting this fact, we propose a watermarking approach that embeds the watermark energy into the image periphery according to foveation-based HVS contrast thresholds.
