An Implementation of Reversible Watermarking for Still Images
This paper presents a reversible data hiding algorithm. It provides good capacity by exploiting the correlation between neighboring pixels. Its application is appropriate in medical, cartographic and forensic images because it's possible to recover the original image and what's more the watermarked image is of very good quality so it can be used in some cases not very demanding. Its applications include authentication, integrity control, or inserting metadata.
