i create a gui there is two image upload button for two different axes now i want to convert this two image in binary form with help of one process button.....could any one help me .how to create?bellow is the code

% --- Executes on button press in pushbutton1. function pushbutton1_Callback(hObject, eventdata, handles) % hObject handle to pushbutton1 (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({'*.bmp';'*.jpg';'*.gif';'*.*'}, 'Pick an Image File'); S = imread([pathname,filename]); axes(handles.axes1); imshow(S); handles.f=[pathname,filename]; guidata(hObject, handles);

% --- Executes on button press in pushbutton2. function pushbutton2_Callback(hObject, eventdata, handles) % hObject handle to pushbutton2 (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({'*.bmp';'*.jpg';'*.gif';'*.*'}, 'Pick an Image File'); S = imread([pathname,filename]); axes(handles.axes2); imshow(S); handles.f=[pathname,filename]; guidata(hObject, handles);

now the process button can convert two different image to binary form..........................

% --- Executes on button press in Process. function Process_Callback(hObject, eventdata, handles) % hObject handle to Process (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, 'f') % convert to binary binary_image = im2bw( imread(handles.f) ); %Thinning thin_image=~bwmorph(binary_image,'thin',Inf); figure;imshow(thin_image);title('Thinned Image');
