Geometrically robust image watermarking using scale invariant feature transform

qq_77101 27 0 PDF 2021-02-27 05:02:42

In order to resist geometric attacks, a robust image watermarking algorithm is proposed using scale-invariant feature transform (SIFT) and Zernike moments. As SIFT features are invariant to rotation and scaling, we employ SIFT to extract feature points. Then circular patches are generated using the
