DWT-DCT-SVD based watermarking
Some works are reported in the frequency domain watermarking using Single Value Decomposition (SVD). The two most commonly used methods are based on DCT-SVD and DWTSVD. The commonl...

Geometrically invariant watermarking: synchronization through circular Hough transform
This paper addresses a geometrically invariant watermarking method for digital images. Most previous watermarking algorithms perform weakly against geometric distortions, which des...

Geometrically Invariant Image Watermarking in the DWT Domain
Watermark resistance to both geometric attacks and lossy compressions is a fundamental issue in the image watermarking community. In this paper, we propose a DWT (Discrete Wavelet ...
