%ILABEL	Label an image
%
%		li = ilabel(image [, connect])
%		[li,maxlabel] = ilabel(image [, connect])
%		[li,maxlabel,parents] = ilabel(image [, connect])
%
%	Perform connectivity analysis and return a label image LI, same size as 
%	IMAGE where each pixel value represents the label of the region of its
%	corresponding pixel in IMAGE.
%
%	Connectivity is performed using 4 or 8 nearest neighbour as controlled
%	by the optional connect argument.  Default is 4 way but can be changed
%	to 8.  The function compares the pixel values so the image can be 
%	greyscale or binary.
%
%	Also returns the maximum label assigned to the image.  Labels lie in
%	the range 1 to MAXLABEL.
%
%	The third form also returns region hierarchy information.  The
%	value of parents[i] is the label of the 'parent' or enclosing
%	region of region i.  A value of 0 indicates that the region has
%	no enclosing region.
%
% SEE ALSO:	imoments iblobs
%
% LIMITATIONS:	should allow for different connectivity modes
