LABEL2COLOR Convert Label Matrix to RGB Image with specified properties.

%LABEL2COLOR Convert Label Matrix to RGB Image with specified properties.
% RGB = LABEL2COLOR(X) converts a label matrix X into a color RGB image
% with default properties for the purpose of visualizing the labeled regions.
%
% RGB = LABEL2COLOR(X,PARAM1,VAL1,PARAM2,VAL2,___) converts a label matrix X,
% specifying parameters and corresponding values that control various aspects of the RGB image.
% Parameter case does not matter.
%
% PROPERTIES can be a comma-separated list of strings
% 'ColorMap' - colormap (default 'jet')
% 'ZeroColor' - zero color (background, uint8/double, default [0 0 0])
% 'EdgeColor' - edge color (uint8/double, default [255 255 255])
% 'EdgeWidth' - edge width (default 1)
%
% Class Support
% -------------
% The input label matrix X can have any numeric class. It must contain
% finite nonnegative integers. RGB is uint8.
%
% Example 1
% ---------
% RGB = label2color(X);
%
% Example 2
% ---------
% RGB = label2color(X,'colormap','summer');
%
% Example 3
% ---------
% RGB = label2color(X,'ColorMap','hot','ZeroColor',[0 0 1],'EdgeColor',[1 1 1],'EdgeWidth',3);
