Near-lossless reversible robust digital watermarking scheme based on singular value decomposition
Zhiquan Li · Journal of Optoelectronics·laser · 2009
A new near-lossless robust digital watermarking scheme based on singular value decomposition(SVD)and reversible data hiding is proposed.The host image is firstly partitioned into non-overlapping blocks,and the watermark is embedded in the U component after the SVD transformation is performed on the blocks.Secondly,the information of the recoverable cover images is hiding in the watermarked image by reversible information hiding method.In the process of watermark extraction and image recovery,the cover image is not needed.The experimental results have confirmed that this scheme can recover the cover image,is highly robust against the attack from JPEG compression,noise perturbation,low-pass filtering,cropping,rotation.
