i tried using 2 push buttons to start and stop my video processing. But the GUI disappears as soon as i click start. whats seems to be the problem? here is the executable part of my code
clc;
close all;
clear all;
source = videoinput('winvideo');
set(source, 'ReturnedColorSpace', 'RGB');
set(source, 'FramesPerTrigger', 1);
set(source, 'TriggerRepeat', 50);
triggerconfig(source, 'manual');
start(source);
thresh = 15/255;
pause(2);
trigger(source);
bg = getdata(source,1,'double');
bg_bw = rgb2gray(bg);
fr_size = size(bg);
width = fr_size(2);
height = fr_size(1);
f = zeros(height, width);
for i=1:50
trigger(source);
fr=getdata(source,1,'double');
fr1=fr(:,:,:,1);
fr_bw1=rgb2gray(fr1);
bg_fr_diff = abs((double(bg_bw)) - (double(fr_bw1)));
for j=1:width % if fr_diff > thresh pixel in foreground
for k=1:height
if (bg_fr_diff(k,j) > thresh)
f(k,j) =255;
else
f(k,j) = 0;
end
end
end
figure(1),subplot(2,1,1),imshow(fr1)
subplot(2,1,2),imshow(uint8(f))
bg_bw=fr_bw1

Get rid of the "clear all" and "close all".

+1. Another example for the negative effects of the excessively used brute clearing header. Who does beginners tell to extinguish all existing values before running some code?

I've accepted this answer. It would be better, if the OP cares about selecting an accepted answer or at least reply, if this solves the problem already.
