A Feature-Based Robust Digital Image
Watermarking Scheme
AIM:
The main aim of the project is to design and implement “A Feature-Based
Robust Digital Image Watermarking Scheme”
ABS!RA"!:
The effectiveness of a digital watermarking algorithm is indicated by the
robustness of embedded watermarks against various attacks. Improving the
robustness of a watermark so as to withstand attacks has been one of the main
research objectives in digital image watermarking. The two issues of existing
feature-based schemes that have to be addressed are: one is avoiding repeated
selection of robust regions for watermarking to resist similar attacks, and the other
is the difficulty of selecting the most robust and smallest feature region set to be
watermarked. In order to achieve robustness, an overall architecture for a feature-
based robust digital image watermarking scheme is designed. ! simulated
attacking procedure is performed using predefined attacks to evaluate the
robustness of every candidate feature region selected. "omparing with some well
known feature-based methods, the proposed method exhibits better performance in
robust digital watermarking.

! novel techni/ue centered on the simulated attacking approach is
developed to select the most ade/uate feature regions for robust digital
image watermarking under the limitation of preserving image /uality.
In comparison with other feature-based watermarking methods, the
robustness against various attacks is significantly improved by the proposed
method, and the image /uality after watermarking is well-preserved.
