RST Resilient Watermarking Scheme Based on DWT-SVD and Scale-Invariant Feature Transform

Currently, most digital image watermarking schemes are affected by geometric attacks like rotation, scaling, and translation (RST). In the watermark embedding process, a robust watermarking scheme is proposed against RST attacks. In this paper, three-level discrete wavelet transform (DWT) is applied...
