%讀入兩幅圖像
imgA=imread（‘nameA.jpg‘）;
imgB=imread（‘nameB.jpg‘）;
%精度轉換
imgA=double（imgA）;
imgB=double（imgB）;
%健壯性判斷
[imgArowimgAcol]=size（imgA）;
[imgBrowimgBcol]=size（imgB）;
[imgArowimgAcol]
[imgBrowimgBcol]
if?imgArow<1||imgAcol<1||imgBrow<1||imgBcol<1
????error（‘您的輸入有誤！維數不能小于1‘）;
elseif?imgArow~=imgBrow||imgAcol~=imgBcol
????error（‘您輸入德矩陣維數不相等！‘）;
end
%求兩幅圖像的均值差
imgA=imgA-mean2（imgA）;
imgB=imgB-mean2（imgB）;
%求求兩幅圖像的相關系數
CC=sum（sum（imgA.*imgB））./（sqrt（sum（sum（imgA.^2）））.*sqrt（sum（sum（imgB.^2））））;
