Improvement in the embedding capacity ultimately results into the improved robustness of the technique. We worked mainly with [...]

ABSTRACT
Watermarking in medical images is a new area of research and some works in this area have been reported world wide recently. Most of the works are on the tamper detection of the images and embedding of the Electronics Patient Record (EPR) data in the medical images. Watermarked [...]
