An adaptive color image watermarking using RDWT-SVD and ...
Color image watermarking techniques reported in the literature have used either a binary, a gray or pseudo-random sequence as a watermark, for example, Roy.et al. in presents an SVD based location specific in RDWT domain using YCbCr color space. An Arnold scrambled grayscale logo is used to embed in the Y component of host image blockwise.
A robust semi-blind watermarking for color images based on ...
In this paper, a robust semi-blind watermarking scheme for color images, based on multiple decompositions is proposed to preserve the copyrights of the owner. Using multiple decompositions, the gray watermark is embedded into a host color image. Prior to that, to enhance security the gray watermark is encrypted with Arnold transform and SVD by generating secret keys....
