Read in each frame, cast it to double, and accumulate, then divide to get the average.

for k = 1 : numberOfFrames
  % read in frame with domcomread() 
  if k == 1
  sumFrame = double(thisFrame);
  else
    sumFrame = sumFrame + double(thisFrame);
  end
end
averageFrame = sumFrame / numberOfFrames;
