Robust reversible watermarking for grayscale medical images

Abstract

Robust reversible watermarking algorithms applied to protect medical imaging from misdiagnosis for any slight distortion. It suited for tasks like copyright protection while preserving the visual quality of watermarked images. It also shows robustness against transmission errors. We propose a novel robust reversible watermarking technique for grayscale medical images. We investigate the high embedding capacity watermarking technique also keeping low distortion in the watermarked images. We demonstrate the accuracy of the reversibility even in error-prone transmission channels. Our simulations show that the proposed technique effectively retains the perceptual quality. © Springer Nature Singapore Pte Ltd. 2020.
