Histogram equalization "I'=M(I)" then the implementation is by image change. In most cases palette change is better as it preserves the original data. Modifications of this method use multiple histograms, called subhistograms, to emphasize local contrast, rather than overall contrast. Examples of such methods include adaptive histogram equalization, "contrast limiting adaptive histogram equalization" or CLAHE, multipeak histogram equalization (MPHE), and multipurpose beta optimized bihistogram equalization (MBOBHE). The goal of these methods, especially MBOBHE, is to improve the contrast without producing brightness mean-shift and detail loss artifacts by modifying the HE algorithm. A signal transform equivalent to histogram equalization also seems to happen
