Robust digital image watermarking
thesisposted on 2015-06-01, 00:00 authored by T Zong
This research presents a novel rank based image watermarking method and improved moment based and histogram based image watermarking methods. A high-frequency component modification step is also proposed to compensate the side effect of commonly used Gaussian pre-filtering. The proposed methods outperform the latest image watermarking methods.
