Example image ('Angel') from the data-set [48] (see Table II). Top: the input image and original ACE enhancement. Second line: four approximations of ACE: FACE, Gatta et al. [25], and polynomial and interpolation-based methods of Getreuer [28]. Bottom: the difference images versus ACE, color coded with the Euclidean distance in the RGB space ( RGB ), on a scale from 0 to 255.
