Abstract |
|
To overcome the problem of color image this paper proposes a watermarking scheme in B domain of color image DWT-SVD. The singular values of B channel are modified by singular value of watermark. Low frequency sub-band coefficients are less robust to geometrical distortion and histogram equalization while High frequency sub-bands are resistant to another attacks. Hence embedding the same watermark in all bands will make it difficult to remove the watermark from all frequency sub-bands. So here we embed watermark in all four sub-bands (LL, HL, LH, HH) to increase robustness. Set of image processing attacks are applied to watermarked image to check the scheme performance. |
