A robust watermark embedding in smooth areas

A robust watermark embedding in smooth areas

Robustness is one of the most important properties of watermarking, the watermark should be readable from images that underwent common attacks such as lossy compression or Joint Photographic Experts Group (JPEG). While many publications consider the relation between smoothness and quality of the ima...
