A new spatial perceptual mask for image watermarking
This paper develops a new mask in the spatial domain for image watermarking. The mask exploits the properties of human visual system with respect to background luminance, the edge...

On the Optimal Structure of Watermark Decoders Under Desynchronization Attacks
Designing watermarking codes that can withstand geometric and other desynchronization attacks is a notoriously difficult problem. One may ask whether these difficulties are due to...

On Optimal Watermarking Schemes in Uncertain Gaussian Channels
This paper describes the analytical derivation of a new watermarking algorithm satisfying optimality properties when the distortion of the watermarked signal is caused by a Gaussi...

Improved watermark detection robust to camcorder capture based on quadrangle estimation
In this paper, we propose a blind watermark detection scheme which is robust against composite geometric distortions. The composite geometric distortions mean that an image or a v...
