Novel image watermarking method based on FRWT and SVD
Zhihai Zhuo · International Journal of Electronic Security and Digital Forensics · 2017
The fractional wavelet transform (FRWT) is a generation of WT associated with the convolution theorem in fractional Fourier transform (FRFT) domain. The FRWT not only inherits the advantages of multi-resolution analysis of the wavelet transform (WT), but also has the capability of image representations in the FRFT domain. In view of the above characteristics, a novel digital image watermarking method based on FRWT and SVD is proposed in this paper. The experimental results show that this method is robust to geometric attacks and image processing attack.
