Contrast-limited adaptive histogram equalization (CLAHE). collapse . Without the clip limit, the adaptive histogram equalization technique could produce results that, in some cases, are worse than the original image.  Zuiderveld, Karel. Contrast limited adaptive histogram equalization KJ Zuiderveld, AHJ Koning, MA Viergever CJ Bakker, HF Smits, C Bos, R van der Weide, KJ Zuiderveld. Improve contrast locally by performing adaptive histogram equalization.  K. Zuiderveld: Contrast Limited Adaptive Histogram Equalization. In: P. Heckbert.

These areas are characterized by a high peak in the histogram of the particular image tile due to many pixels falling inside the same gray level range.
Number of rectangular contextual regions tiles into which adapthisteq divides the image, specified as a 2-element vector of positive integers. Trial Software Product Updates.
Contrast enhancement limit, specified as a limired scalar in the range [0, 1]. Specify optional comma-separated pairs of Name,Value arguments. Output intensity image, returned as a 2-D array of the same limuted as the input image I.

Journal of Magnetic Resonance Imaging 8 1, Computer vision, graphics, and image processing 39 3, Without the clip limit, the adaptive histogram equalization technique could produce results that, in some cases, are worse than zjiderveld original image. New citations to this author. The optimal number of tiles depends on the type of the input image, and it is best determined through experimentation.
The distribution you select should depend on the type of the input image.
