I need to create a series of mean images. So I created the following code

function [meanbgimage] = impostprocbg(bgpath)
%Calculates the mean backgroung image
 cd(bgpath)
 bglist=dir('*.tif');
 I0 = imread(bglist(1).name);
 sumbgImage = im2double(I0); % Inialize to first image.
 k=1;
 for i=2:length(bglist) % Read in remaining images
  nameused = bglist(i).name;
  img = imread(nameused);
%   Image = imcomplement(Image);
  img=im2double(img);
%   img=wiener2(img);
  sumbgImage = im2double(imadd(sumbgImage,img));
  clear img
  if mod(i,100)==0
  meanbgimage(:,:,k) = imdivide(sumbgImage,100);
  j = meanbgimage(:,:,k);
  j = im2uint16(j);
  meanbgimage(:,:,k) = j;
  sumbgImage = zeros(512,512);
  k=k+1;
  end
  i
  end;

The problem is that I need meanbgimage to be an array of uint16 2D arrays. However, this code returns meanbgimage as a double. Does anybody knows what should I do?
