文档介绍：function [I_SSD,I_NCC,Idata]=template_matching(T,I,IdataIn)
% TEMPLATE_MATCHING is a cpu efficient function which calcu0,50);
% % Get a small volume as template

% % Calculate SDD between template and image
% I_SSD=template_matching(T,I);
% % Find maximum correspondence
% [x,y,z]=ind2sub(size(I_SSD),find(I_SSD==max(I_SSD(:))));
% disp(x);
