Still-image watermarking robust to local geometric distortions

J.-L. Dugelay, S. Roche, C. Rey, G. Doerr
2006 IEEE Transactions on Image Processing  
In this paper, we propose an original blind watermarking algorithm robust to local geometrical distortions such as the deformations induced by Stirmark.  ...  Geometrical distortions are the Achilles heel for many watermarking schemes.  ...  The difficulty is then to make both approaches work together to be able to cope with any kind of geometric distortion, in particular a combination of global and local geometric attacks.  ...

2020 IEEE Access  
This paper provides a comprehensive survey of M-IoT with an emphasis on architecture, protocols, and applications. This article starts by providing a horizontal overview of the IoT.  ...  We explore the importance of Quality-of-Experience (QoE) and Quality-of-Service (QoS) for multimedia transmission over IoT.  ...  Watermarking is used to identify the origin of multimedia content, trace illegal distribution, and block unauthorized access by embedding a unique watermark into multimedia content [76] .  ...

Moreover, the introduced DVC scalable schemes show a good robustness to errors as the quality of decoded video steadily decreases with error rate increase.  ...  Further, the issue of privacy protection is addressed for DVC by transform domain scrambling, which is used to alter regions of interest in video such that the scene is still understood and privacy is  ...  Shuiming Ye for his help with the work on the proposed improved side information and hybrid error concealment. Many thanks also to Mr.  ...
