function varargout = GUI(varargin) % GUI MATLAB code for GUI.fig % GUI, by itself, creates a new GUI or raises the existing % singleton*. % % H = GUI returns the handle to a new GUI or the handle to % the existing singleton*. % % GUI('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in GUI.M with the given input arguments. % % GUI('Property','Value',...) creates a new GUI or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before GUI_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to GUI_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES

% Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ... 'gui_Singleton', gui_Singleton, ... 'gui_OpeningFcn', @GUI_OpeningFcn, ...

% --- Executes just before GUI is made visible. function GUI_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 GUI (see VARARGIN)
% Choose default command line output for GUI handles.output = hObject;
axes(handles.axes1); vid=videoinput('winvideo', 2); hImage=image(zeros(352,288,3),'Parent' handles.axes1); preview(vid,hImage);
% Update handles structure guidata(hObject, handles);
% UIWAIT makes GUI wait for user response (see UIRESUME) % uiwait(handles.figure1);
