A Robust Multiplicative Watermark Detector for Color Images in Sparse Domain
IEEE Transactions on Circuits and Systems II: Express Briefs(2015)
摘要
In recent years, digital watermarking has facilitated the protection of copyright information through embedding hidden information into the digital content. In this brief, for the first time, a blind multichannel multiplicative color image watermarking scheme in the sparse domain is proposed. In order to take into account the cross correlation between the coefficients of the color bands in the spa...
