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. [1] 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. [1] K. Zuiderveld: Contrast Limited Adaptive Histogram Equalization. In: P. Heckbert.

For zuiderfeld, underwater imagery appears to look more natural when the Rayleigh distribution is used. Algorithms CLAHE operates on small regions in the image, called tilesrather than the entire image. Value Description ‘uniform’ Create a flat histogram. Number of rectangular contextual regions tiles into which adapthisteq divides the image, specified as a 2-element vector of positive integers.

Scale values to the range expected by the adapthisteq function, [0 1]. Both M and N must be at least 2.
