Robust image watermarking on Triangle grid of feature points

Abstract

The paper presents a digital image watermarking technique robust to geometric distortions. This technique is based on a novel procedure of building a set of primitives for embedding using Delaunay triangulation on a set of feature points, and uses additive embedding method with linear correlation detector. Much attention is paid to the problem of choosing the most appropriate feature points detector. Conducted experiments demonstrate robustness of the proposed method to a range of geometric distortions.
