- W3017630880 abstract "The most traditional watermark techniques are used widely in information hiding technology. However, these techniques require some information of origin images to extract it from the cover image in frequency domain. This paper introduces a new blind watermark technique for embedding three watermark gray images into a color cover image based on Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD). The proposed technique is consists of three phases: Firstly, the three gray images are embedded into SVD components of cover color image to produce watermarked image. Secondly, the watermarked image is again embedded into the low frequency (DWTDCT) domains of one component of RGB origin cover image to produce the final resultant watermarked image. Finally, the three watermark images are blind extracted in the reverse operations without require to their SVD components. The implementation of the proposed technique is a perceptible improvement of experimental results compared with the recently watermarked techniques with respected to PSNR and Normalized Correlation (NC). This technique is also a robust to noise and intentional attacks." @default.
