[PDF][PDF] Hybrid robust watermarking techniques based on DWT, DCT, and SVD
International Journal of Advanced Electrical and electronics engineering, 2013•academia.edu
In this paper, we propose a hybrid watermarking scheme for digital images based on
singular value decomposition (SVD). The two key aspects of watermarking schemes are
copyright protected and robustness. In this, we are embedded the principal components of
the watermark in the DCT domain of DWT subband of host image, for providing copyright
protection as well as reliability. Since Scaling factor is an image dependent. Experimental
results are provided to illustrate that the proposed scheme is able to withstand a variety of …

Abstract
In this paper, we propose a hybrid watermarking scheme for digital images based on singular value decomposition (SVD). The two key aspects of watermarking schemes are copyright protected and robustness. In this, we are embedded the principal components of the watermark in the DCT domain of DWT subband of host image, for providing copyright protection as well as reliability. Since Scaling factor is an image dependent. Experimental results are provided to illustrate that the proposed scheme is able to withstand a variety of image processing attacks as well as imperceptibility.
