%X <p>In order to improve the invisibility and robustness of digital watermarking algorithm, a new watermark was designed and embedded into large coefficients of low frequency of maximum entropy subband and small coefficients of low frequency of minimum entropy subband. And the strong directional sensitivity of extended discrete shearlet transform was introduced into digital watermarking as well. On this basis, a two-stage extended discrete shearlet transform of digital watermarking algorithm was proposed. Experiments show that the algorithm not only has strong invisibility, after adding a series of attacks, the watermark can still be extracted. The algorithm has strong invisibility and robustness.</p>
