%X A novel block-based digital watermarking scheme in non-subsampled shearlet transform was proposed. The directional features of the NSST was utilized and the entropy was taken as the criterion of selecting the embedded blocks in images. Besides, this scheme applied singular value decomposition to embed the binary watermark logo. The algorithm not only solved the problem that the invisibility and the robustness in multiscale analysis watermarking algorithm could not be taken into account, but also fully showed the superiority comparing with other previous schemes. Experiment results demonstrated that the peak signal to noise ratio was above 51 dB and most of normalized correlation values were higher than 0.93. The imperceptibility and robustness performance was experimentally proved to be enhanced.
