摘要
Watermarking is the technique to solve the issue of copyright degradation, but this has to be resolved by keeping a steady check on the imperceptibility and robustness which incur to be its main objectives. In order to accomplish these objectives the usage of a hybrid transform is adopted in this paper, the idea behind using a hybrid transform is that the cover image is modified in its singular values rather than on the DWT sub-bands, therefore the watermark makes itself vulnerable to vivid attacks. Experimental results are available to support the study.
