Perceptual Watermarking should take full advantage of the results from human visual system (HVS) studies. Just noticeable difference (JND), which refers to the maximum difference that the HVS does not perceive, gives us a way to model the HVS

In this paper, we propose a new perceptual model for balanced multiwavelet (BMW) transforms. The latter transform achieves simultaneous orthogonality and symmetry without requiring any input prefiltering. The proposed model is derived using m
