PDF digital watermarking grayscale photocopy detection of printed documents

Digital watermarking is a growing research area to mark digital content (image, audio, video,etc.) by embedding information into the content itself. As a result, this technique provides additional and useful features for many application fields. In addition, digital watermarking is also used to prov...
