function out = adapthisteq(varargin)
%ADAPTHISTEQ Contrast-limited Adaptive Histogram Equalization (CLAHE).
% ADAPTHISTEQ enhances the contrast of images by transforming the
% values in the intensity image I. Unlike HISTEQ it operates on small
% data regions (tiles) rather than the entire image. Each tile‘s
% contrast is enhanced so that the histogram of the output region
% approximately matches the specified histogram. The neighboring tiles
% are then combined using bilinear interpolation in order to eliminate
% artificially induced boundaries. The contrast especially
% in homogeneous areas can be limited in order to avoid amplifying the
% noise which might be present in the image.
%
% J = ADAPTHISTEQ(I) Performs CLAHE on the intensity image I.
%
% J = ADAPTHISTEQ(IPARAM1VAL1PARAM2VAL2...) sets various parameters.
% Parameter names can be abbreviated and case does not matter. Each
% string parameter is followed by a value as indicated below:
%
% ‘NumTiles‘ Two-element vector of positive integers: [M N].
% [M N] specifies the number of tile rows and
% columns. Both M and N must be at least 2.
% The total number of image tiles is equal to M*N.
%
% Default: [8 8].
%
% ‘ClipLimit‘ Real scalar from 0 to 1.
% ‘ClipLimit‘ limits contrast enhancement. Higher numbers
% result in more contrast.
%
% Default: 0.01.
%
% ‘NBins‘ Positive integer scalar.
% Sets number of bins for the histogram used in building a
% contrast enhancing transformation. Higher values result
% in greater dynamic range at the cost of slower processing
% speed.
%
% Default: 256.
%
% ‘Range‘ One of the strings: ‘original‘ or ‘full‘.
% Controls the range of the output image data. If ‘Range‘
% is set to ‘original‘ the range is limited to
% [min(I(:)) max(I(:))]. Otherwise by default or when
% ‘Range‘ is set to ‘full‘ the full range of the output
% image class is used (e.g. [0 255] for uint8).
%
% Default: ‘full‘.
%
% ‘Distribution‘ Distribution can be one of three strings: ‘uniform‘
% ‘rayleigh‘ ‘exponential‘.
% Sets desired histogram shape for the image tiles by
% specifying a distribution type.
%
% Default: ‘uniform‘.
%
% ‘Alpha‘ Nonnegative real scalar.
% ‘Alpha‘ is a distribution parameter which can be supplied
% when ‘Dist‘ is set to either ‘rayleigh‘ or ‘exponential‘.
%
% Default: 0.4.
%
% Notes
% -----
% - ‘NumTiles‘ specify the number of rectangular contextual regions (tiles)
% into which the image is divided. The contrast transform function is
