Reversible data hiding with contrast enhancement using adaptive histogram shifting and pixel value ordering
作者:
Highlights:
• >Adaptive histogram shifting improves the image contrast for RDH methods.
• Bidirectional histogram pre-shifting alleviates visual image distortion.
• The pixel value ordering technique increases the embedding capacity.
• An alternative way can better evaluate the marked image quality.
