%  PROGRAM
% vicanon - Inf-Canonical Operator
%
%  DESCRIPTION
% .I vicanon
% will do the n-canonical dual transformation of an input image by a set of n structuring elements, generated after two input structuring elements.
% The number of structuring elements is the integer part of 8 (maximum number of struct. els. achieved by rotation of one struct. el.) divided by r (the rotation step). 
% 
% The output image data type will be the same as that of the highest data type 
% of the input image.
% 
% Some useful pairs of structuring elements:
% 
%                       0 0 0    0 0 0
%   End Points          0 1 0    1 0 1
%                       0 0 0    1 1 1
% 
%                       0 0 0    1 1 1
%   Isolated Points     0 1 0    1 0 1
%                       0 0 0    1 1 1
% 
%                       1 0 0    0 1 1 
%   Triple Points       0 1 1    1 0 0
%                       1 0 0    0 1 1
% 
%                       1 0 1    0 1 0
%   Triple Points       0 1 0    1 0 1
%                       1 0 0    0 1 1
% 
%                       1 0 0    0 1 1
%   Triple Points       0 1 0    1 0 1

%  EXAMPLES
% vicanon -i ball.xv -str1 b272.str -str2 b273.str -r 2 -o outimage.xv
% 
% Will do the n-canonical dual transformation of image "ball.xv" by a set of 4 structuring elements, generated after b272.str and b273.str, with the resulting image written to "outimage.xv".
%
%  "SEE ALSO"
%
%  RESTRICTIONS 
% .I vicanon
% can be defined for all data types supported by Khoros, but at the moment it has been implemented just for the bit and unsigned char types.
% The structuring elements are subsets of the 3x3 matrix and the origin is always at the center of this matrix.
