Özet

This paper presents a novel optimal watermarking scheme based on singular value decomposition (SVD) using differential evolution algorithm (DE). The singular values (SVs) of the host image are modified to embed the watermark image by employing multiple scaling factors (SFs). Modifications are optimised using DE to obtain the highest possible robustness without losing the transparency. Experimental results show both the significant improvement in transparency and the robustness under attacks.
