A Novel Hybrid Reversible-Zero Watermarking Scheme to Protect Medical Image

IEEE Access, 2022
The verification of copyright and authenticity for medical images is critical in telemedical applications. Watermarking is a key technique for protecting medical images and can be mainly divided into three categories: region of interest (ROI) lossless ...

Reversible Watermarking Using Statistical Information [PDF]

EURASIP Journal on Advances in Signal Processing, 2010
In most reversible watermarking methods, a compressed location map is exploited in order to ensure reversibility. Besides, in some methods, a header containing critical information is appended to the payload for the extraction and recovery process.
