readIm = stDehaze.readIm;
onlineMode = stDehaze.onlineMode;
if onlineMode
  triggerconfig(vidObj, 'manual');

  t1 = tic;
  tmp = readIm(vidObj);
  if isReSz 
      tmp = imresize(tmp, reSz);
  end
  
  tmp = im2double(tmp);
  tmp1 = real_timeSerial_dehazing(tmp);
  t1 = 1/toc(t1);
  fprintf('frm/sec@Org=%0.5f \n',t1);
