In this paper we propose a new invisible, non-blind digital watermarking scheme for color images based on singular vector domain (SVD). In this new approach, same or different watermarks can be embedded into the three color ...

Most of the well known algorithms for watermarking of digital images involve transformation of the image data to Fourier or singular vector space. In this paper, we introduce watermarking in Hilbert transform domain for ...
