this is my screenshot http://befunkycartoonizer.s3.amazonaws.com/C2161383-1365961177large.jpg

this is my code

% --- Executes just before Based is made visible. function Based_OpeningFcn(hObject, eventdata, handles, varargin) % This function has no output args, see OutputFcn. % hObject handle to figure % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) % varargin command line arguments to Based (see VARARGIN)

% Choose default command line output for Based handles.output = hObject;

handles.video = videoinput('winvideo', 1); handles.video.ReturnedColorspace = 'rgb'; handles.video.FramesPerTrigger = Inf;

% Update handles structure guidata(hObject, handles);

% UIWAIT makes Based wait for user response (see UIRESUME) % uiwait(handles.figure1);

% --- Outputs from this function are returned to the command line. function varargout = Based_OutputFcn(hObject, eventdata, handles) % varargout cell array for returning output args (see VARARGOUT); % hObject handle to figure % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure handles.output = hObject; varargout{1} = handles.output;

% --- Executes on button press in Camera. function Camera_Callback(hObject, eventdata, handles) % hObject handle to Camera (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) if strcmp(get(handles.Camera,'String'),'Start Camera') % Camera is off. Change button string and start camera. set(handles.Camera,'String','Stop Camera') start(handles.video)

else % Camera is on. Stop camera and change button string. set(handles.Camera,'String','Start Camera') stop(handles.video)

end
