A procedure for image watermarking in the presence of compressive sampling is proposed. The randomly chosen measurements from image blocks are used to carry the watermark. The image reconstruction based on a set of watermarked measurements is performed using the total variation minimization algorithm, allowing good quality of recovered image. The watermark can be efficiently detected within the recovered...
A procedure for image watermarking based on the Hermite projection method is proposed. The coefficients obtained by the Hermite expansion are used for watermark embedding. In the same time, the Hermite projection method provides efficient compression approach, since the image can be recovered by using smaller number of Hermite coefficients. The efficiency and robustness of the proposed procedure is...
