% Configuration file #1 for DeformableRegistration1.cxx
% 
% This example demonstrates the setup of a basic registration 
% problem that does NOT use multi-resolution strategies.  As a 
% result, only one value for the parameters between 
% (# of pixels per element) and (maximum iterations) is necessary.
% If you were using multi-resolution, you would have to specify
% values for those parameters at each level of the pyramid.  
%
% Note: the paths in the parameters assume you have the traditional 
% ITK file hierarchy as shown below:

% ---------------------------------------------------------
% Parameters for the single- or multi-resolution techniques
% ---------------------------------------------------------
1	% Number of levels in the multi-res pyramid (1 = single-res)
1	% Highest level to use in the pyramid
 1 1    	% Scaling at lowest level of pyramid
 4		% Number of pixels per element
 1.e4 	        % Elasticity (E)
 1.e4 	        % Density x capacity (RhoC)
 1		% Image energy scaling (gamma) - sets gradient step size
 2		% NumberOfIntegrationPoints
 1  		% WidthOfMetricRegion
 20		% MaximumIterations
% -------------------------------
% Parameters for the registration

0 0.99  % Similarity metric (0=mean sq, 1 = ncc, 2=pattern int, 3=MI, 5=demons)
1.0	% Alpha
0	% DescentDirection (1 = max, 0 = min)
0	% DoLineSearch (0=never, 1=always, 2=if needed)
