Comments Off on Reversible Image Data Hiding with Contrast Enhancement
Posted in: IEEE 2017, MATLAB
Reversible Image Data Hiding with Contrast Enhancement ABSTRACT: In this letter, a novel reversible data hiding (RDH) algorithm is proposed for digital images. Instead of trying to keep the PSNR value high, the proposed algorithm enhances the contrast of a host image to improve its visual quality. The highest two bins in the histogram are […]
