How to have 2 different appearances to Axes4 and Axes5 for SKIN DETECTION? Why Error?

% --- Executes on button press in pushbutton10.
function pushbutton10_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton10 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

proyek=guidata(gcbf);
I=get(proyek.axes2,'Userdata');
I=get(proyek.axes3,'Userdata');

img_ycbcr = rgb2ycbcr(I);
Cb = img_ycbcr(:,:,2);
Cr = img_ycbcr(:,:,3);

img_ycbcr2 = rgb2ycbcr(J);
Cb = img_ycbcr2(:,:,2);
Cr = img_ycbcr2(:,:,3);

set(proyek.figure1,'CurrentAxes',proyek.axes4);
set(proyek.figure1,'CurrentAxes',proyek.axes5);

set(imshow(img_ycbcr));
set(imshow(img_ycbcr2));

set(proyek.axes4,'Userdata',img_ycbcr);
set(proyek.axes4,'Userdata',img_ycbcr2);

redo_Callback(hObject,eventdata, handles);

In your 3rd line of the code again your specifying I.

I=get(proyek.axes3,'Userdata');

I hope that needs to change to

J=get(proyek.axes3,'Userdata');

Undefined function 'redo_Callback' for input arguments of type 'struct'.

Error in SmarthomeIsyarat>pushbutton10_Callback (line 230) redo_Callback(hObject,eventdata, handles);

Error in gui_mainfcn (line 96) feval(varargin{:});

Error in SmarthomeIsyarat (line 42) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)SmarthomeIsyarat('pushbutton10_Callback',hObject,eventdata,guidata(hObject))
