Wavelet based watermarking method fordigital images using the human visual system
Kim, Kwon, Rae‐Hong Park · Electronics Letters · 1999
A wavelet based multiresolution watermarking method using the human visual system (HVS) is proposed, with the number of watermarks embedded proportional to the energy contained in each band. Experiments show that the proposed three-level wavelet based watermarking method is robust to some attacks such as, for example, joint photographic experts group (JPEG) compression, smoothing and cropping, collusion.
