I have created a gui to insert video stream from webcam based on the code from
I have previously used rectangle function in normal figures with imshow and hold on, to put bounding boxes to track human. Now I want to use the rectangle function in gui. I tried displaying in a small while loop for testing. But Im not getting it.
Code:
function myCameraGUI_OpeningFcn(hObject, eventdata, handles, varargin)handles.output = hObject;handles.video = videoinput('winvideo', 2);set(handles.video,'TimerPeriod', 0.05, ...'TimerFcn',['if(~isempty(gco)),'...'handles=guidata(gcf);'... % Update handles'image(getsnapshot(handles.video));'... % Get picture using GETSNAPSHOT and put it into axes using IMAGE'set(handles.cameraAxes,''ytick'',[],''xtick'',[]),'... % Remove tickmarks and labels that are inserted when using IMAGE'else '...'delete(imaqfind);'... % Clean up - delete any image acquisition objects'end']);triggerconfig(handles.video,'manual');handles.video.FramesPerTrigger = Inf; % Capture frames until we manually stop it
% Update handles structure
guidata(hObject, handles);% UIWAIT makes mycameragui wait for user response (see UIRESUME)
uiwait(handles.myCameraGUI);%------
%Callback Fn for startCamera Button
function startStopCamera_Callback(hObject, eventdata, handles)if strcmp(get(handles.startStopCamera,'String'),'Start Camera') % Camera is off. Change button string and start camera.
set(handles.startStopCamera,'String','Stop Camera') start(handles.video) i=1; x3=500; y3=300; while(i<20) rectangle('Position',[x3,y3,10,10],'EdgeColor','r','LineWidth',1); i=i+1 endelse % Camera is on. Stop camera and change button string.
set(handles.startStopCamera,'String','Start Camera') stop(handles.video)end
