[HELP] how to close figure automatic

Hi, i have code that i used to detect face. When there is no face, it must return to the begining of the program. My problem when there is no face in front of the camera, i must close the figure first to make the program continue. This is my code :

   clc
   clear all
   % Initiate input
vid=videoinput('winvideo',2,'RGB24_640X480'); 
set (vid,'SelectedSourceName','input1');
vid.ReturnedColorSpace='rgb';
vid.FramesPerTrigger=1;
vid.FrameGrabInterval=200;
vid.TimeOut=200;
preview (vid)
        global sum_bbox; 
        global bbox;
        global FaceFrame;
        global sum_bboxeye;
while (true);
% CAPTURE IMAGE
cla reset
data = getsnapshot(vid);
imwrite(data,'data.jpg');
i   = imread('data.jpg');
%FUNGSI FACE DETECTOR
face_detection(i);
[baris1,kolom1]=size(bbox);
if bbox == 0 | baris1>=2
    data = getsnapshot(vid);
    imwrite(data,'data.jpg');
    i  = imread('data.jpg');
    face_detection(i);
    close 
else
% BBOX SEGMENTATION
FFrameCrop= imcrop(FaceFrame,bbox);
subplot (3,2,2); imshow(FFrameCrop); title ('subimage faceframe');
pause(1)
end
end

Help me please.. thx b4

Hi Cahyo,

I don't know how experienced are you, using MATLAB, but don't you think you can close the figure using close gca

close gcf
close all

see MATLAB documentation to understand how to close a specific window.

doc close

I'm sorry if it's the wrong answer, just let me know to remove it and someone esle would definitely answer it.

Hope this helps.

Good Luck!

I think you meant gcf rather than gca

[Salaheddin Hosseinzadeh]

Thanks Sean,

As you mentioned, that should be gcf rather than gca

I'll edit it.
