Hi, I wish to show the video for eye detection in GUI using the vision.CascadeObjectDetector('EyePairBig') by the following code

if true
  EyeDetect = vision.CascadeObjectDetector('EyePairBig');
obj = imaq.VideoDevice('winvideo',1,'YUY2_640x480');
set(obj,'ReturnedColorSpace','rgb');
figure('menubar','none', 'tag', 'webcam');
while(true)
frame=step(obj);
bb=step(EyeDetect,frame);
IEye=insertObjectAnnotation(frame,'rectangle',bb,'Eye');
imshow(IEye,'border','tight')
f=findobj('tag','webcam');
if(isempty(f))
break
end
pause(0.05)
end
release(obj)
end

However i am stuck as from previous examples to preview video in gui i need to use this code

if true
  handles.output = hObject;
axes(handles.axes1);
vid=videoinput('winvideo', 1, 'YUY2_640x480');
himage=image(zeros(640, 480, 3),'parent', handles.axes1);
preview(vid,himage);
end
