Contrast-limited adaptive histogram equalization can also provide subtle edge information but might degrade performance in the screening setting by enhancing the visibility of nuisance information.

Question

Quizplus · Accepted Answer

Contrast-limited adaptive histogram equalization enhances the contrast of an image by limiting the contrast amplification in flat regions and expanding the contrast in steep regions. This can enhance subtle details, including edges, but it can also make nuisance information more visible, which may not be desirable in a screening setting. Therefore, the statement is true.
