Abstract Recent contrast enhancement (CE) methods, with a few exceptions,
predominantly focus on enhancing gray-scale images. This paper proposes a bihistogram shifting contrast enhancement for color images based on the RGB (red,
green, and blue) color model. The proposed method selects the two highest bins
and two lowest bins from the image histogram, performs an equalized number of
bidirectional histogram shifting repetitions on each RGB channel while
embedding secret data into marked images. The proposed method simultaneously
performs both right histogram shifting (RHS) and left histogram shifting (LHS) in
each histogram shifting repetition to embed and split the highest bins while… More >
