Zusammenfassung:Imperceptibility and robustness against attacks are the foremost qualities desired in any image watermarking scheme. In this work, a contrast based image watermarking algorithm is proposed based on a human visual system model. The algorithm is designed using concepts from attack modelling, and is tested against different attacks. The presented results show that the algorithm is robust to removal based attacks.
