Considering that the human eye is more sensitive to the distortion in the smooth areas, in this letter, we propose a new histogram shifting strategy for RDH by referring to the general distortion ...

To address this problem, this paper proposes a new JPEG RDH scheme based on block sorting optimization and dynamic iterative histogram modification. We firstly design a block ordering optimization ...

RGB histograms As well as brightness histograms, more sophisticated cameras can display additional histograms for each of the three primary colours: red, green and blue. Colour histograms show the ...

Read images, compute bins, generate image histograms, which involves equalising a 64-bin grayscale histogram and comparing and matching the two histograms.
