We propose an information–theoretic approach to the watermark embedding and detection under limited detector resources. First, we present asymptotically optimal decision regions...

An algorithm is presented which implements image watermarking in the domain of an overcomplete, or redundant, wavelet transform. This algorithm expands on a previous method which ...

Semi-fragile watermarking can be used to detect illegal and local manipulation of images, while being robust towards legal manipulations such as lossy compression. This paper desc...
