CODE
% --- Executes on button press in Recognation.
function Recognation_Callback(hObject, eventdata, handles)
% hObject handle to Recognation (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
CCoeff = corr2(A,B)
if CCoeff > 0.7 % (choose a value < 1) % image 1 and image 2 are compared
msgbox('Both A and B are similar', 'MESSAGE');
else
msgbox('A and B are not similar', 'MESSAGE');
end
ERROR
Error in matching (line 42)

indrani - you haven't posted the full error message but presumably it has something to do with
CCoeff = corr2(A,B)
where A and B aren't defined. How or where have these variables been set previously in your code? Consider adding them to the handles structure so that all callbacks have access to this data. See guidata for details on how you can do this.

Where would you put this call to match in your GUI? How are the inputs to this function defined?
