Robust digital watermarking for coloured images using SVD and DWT technique

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 subbands, therefore the watermark makes itself vulnerable to vivid attacks. Experimental results are available to support the study.
