A SVD-LS Based Watermarking in Transform Domain
Juan Wei · Journal of Anyang Normal University · 2009
The paper proposes an image watermarking algorithm based on singular value decomposition(SVD) and least square method(LS) in transform-domain.It belongs to non-blind watermarking,and embeds the partial information of the watermark image.The simulation results show the algorithm not only is strong enough to resist common image processing,but also has good robustness on geometric attack such as zoom,image cut,rotate,and so on.
