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
