The image is didn't displayed in the axes4.
function pushbutton5_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton5 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[filename pathname] = uigetfile({'*.jpg';'*.bmp'},'Select MRI');
inputimage=strcat(pathname, filename);
axes(handles.axes3)
imshow(inputimage)
% save the updated handles object
guidata(hObject,handles);
% --- Executes on button press in pushbutton6.
function pushbutton6_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton6 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
if isfield(handles,'inputimage')
axes(handles.axes4)
a=rgb2gray(imread(inputimage));
Y=medfilt2(a,[5 5]);
imshow(Y)
end

handles.inputimage = fullfile(pathname, filename);
imshow(handles.inputimage, 'Parent', handles.axes3)

In pushbutton5_Callback(), because that's where you read the variable in. But you assigned it to a local variable which vanishes when the callback function exits. Walter's code attaches it to the handles structure so it will then be available in every other callback.
