Proposing a New Image Watermarking Method Using Shearlet Transform and Whale Optimization Algorithm

Digital images watermarking is a method for data hiding that ensures the security of multimedia data. In these ways, watermark can be digital image or stored within content. The Shearlet transform, multi-resolution and multi-directional conversion, used in images. Due to its superior features, this conversion increase efficiency applications such as paper, SVD transforms are with Whale optimization algorithm obtain most appropriate scaling factor extraction step after applying different types processing attacks. Transform has more transparency than traditional converts. transform also increases robustness operations. results experiments show new presented terms imperceptibility compared methods tested, performs better
