Digital Image Watermarking Techniques: A Review

Mahbuba Begum, Mohammad Shorif Uddin
2020 Information  
Based on the desired applications, several suitable watermarking techniques have been developed to mitigate this concern.  ...  However, it is tough to achieve a watermarking system that is simultaneously robust and secure.  ...  A threedimensional (3D) mesh watermarking scheme has been proposed by Hamidi et al. [48] , which protects copyright information based on mesh saliency and a wavelet transform.  ...
