Redundant-wavelet watermarking with pixel-wise masking
2005
IEEE International Conference on Image Processing 2005
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 employs a traditional, critically sampled wavelet transform coupled with perceptually-based watermark casting and optimal Neyman-Pearson detection. Specifically, in the proposed method, the redundancy inherent in the transform facilitates detection of perceptually salient texture local to a given spatial location and
