- W2393400534 abstract "In this paper ,based on permuted image and SVD, we embedded gray watermark in colour image's dwt components. in order to make this algorithm is of better invisibility and very robust , The given color image is split into its three components RGB and a watermark was embedded into blue component of color image. It was found by experiment that the perceptive quality of original image might be better kept when watermark was embedded into blue component than into other color components.A Threshold value was setted,if the diagonal of valuebased on SVD was less than the threshold valve,we can substitute the value of before for the value of the diagonal .The experiments show that the algorithm had a better robustness to JPEG compressiing median filtering,and other attacks." @default.
