How can I get median filtered background image from sequence of video frames? I am trying to store the corresponding pixels values of sequence of frames in respective cells and then to find the median value, but I cannot get values in cells.

files = dir('*.JPG')
img=imread(files(1).name);
img_gray=rgb2gray(img);
E=cell(size(img_gray));
for k = 1:numel(files)
rgb = imread(files(k).name);
gry=rgb2gray(rgb);
for i=1:1:size(gry,1)
for j=1:1:size(gry,2)
E{i,j}=[files(1).name:files(k).name];
med=cellfun(@median,E);
end
end
end

Why is E a cell array and why are you using cellfun?
for k = 1 : numel(files)
rgb = imread(files(k).name);
gry = rgb2gray(rgb);
E = medfilt2(gry);
end
