In this paper, we apply an information-theoretic model, developed for digital image watermarking, to derive the data hiding capacities of image sources in the mapping-domain of non-redundant complex wavelet transforms (NCWTs). Results, based on the same model, have been recently reported for balanced multiwavelet (BMW) transforms. In this model, the underlying statistical model defines the hiding capacity in terms of the distortion constraints imposed on the watermark embedder and the attacker, and the information available to the watermark embedder, to the attacker, and to the watermark decoder. The motivations behind the use of NCWTs is the directionality and phase information provided by such representations.
