Digital Watermarking Hidden Stability Based on Wavelet Transform

In order to solve the stability of digital watermarking and hidden,JND threshold is proposed based on the watermark embedding algorithm,The host image wavelet coefficients do change based on threshold,And to modify the position of the coefficient as a key save and modify the parameters,Image processing due to the small coefficient on the impact produced by PSNR,PSNR is calculated on the threshold…
