Should We Consider Adaptivity in Moment-based Image Watermarking ?
Efstratios Tsougenis, George A. Papakostas · Gate to Computer Science and Research · 2014
The term adaptivity is absent from the state-of-the-art moment-based image watermarking methods.A question to be answered is whether adaptive watermark insertion will guide to the enhancement of image's security (concerning a number of requirements such as robustness, imperceptibility, complexity and capacity).Initially, the term adaptivity is being unfold from dierent perspectives; the selection of the most qualied coecients (considering their order and magnitude) for carrying the watermark information; the selection of the most qualied image region for hosting the
