Abstract |
|
In this paper, we present a robust embedding algorithm for digital watermarking using 5-dimensional wavelet discrete transform (5-WDT) and singular value decomposition (SVD). First of all, we take two images cover color image and secret color image for embedding. On the cover color image, we apply image compression for reducing size and increasing time, then we apply 5-WDT and SVD. And repeat the same process for secret color image. We worked on both color and gray image for embedding. In this algorithm, we improve peak signal noise ratio (PSNR) and mean square error (MSE). In the experimental outcomes, we achieve PSNR value up to 70%. |
