Abstract

At watermarking is developed, The construction proposed in this paper is based on a no subsampled pyramid (NSP) transform and wavelet transform (WT).The result of no subsampled transform is a flexible multiscaleand shift-invariant image decomposition that can be efficiently implemented via the à torus algorithm, the corresponding frame elements for à torus algorithm are regular, symmetric, and the frame is close to a tight one that can implement linear phase filter. Shift-invariance is useful in eliminating the Gibbs phenomenon and increasing the invisibility of watermark. The subsampled wavelet transform obtains a small size low-pass sub band which is embedded watermark, so the watermark can sufficiently spread in image after reconstruction, thereby the robustness and the invisibility of watermark will be improved. We assess the performance of the SSWT in image watermarking, the SSWT compares favourably to other existing methods in the literature on both robustness and invisibility of watermark.
