Using imfill on multiple images

myPath= 'E:\conduit_stl(smooth contour)\Collagen Contour Slices\'; 

fileNames = dir(fullfile(myPath, '*.tif'));

C = cell(length(fileNames), 1);

for k = 1:length(fileNames)

      filename = fileNames(k).name; 

      C{k} = im2bw(imread(filename));

      filled = imfill(C,'holes');

end

I have this code to import multiple images from a folder into MATLAB. Though now I would like to perform a fill on all the images. However, when attempting this, an error stating: "Expected input number 1, I1 or BW1, to be one of these types: double, ... etc" I tried converting the images into double precision, though that just resulted in: "Conversion to double from cell is not possible."

This is most likely due to the structure type, the images are 'housed' in, but I have no idea concerning that.

Help on this would be greatly appreciated.

C(256,256,length(fileNames)) = uint8(0);

C_filled = C;

 se = strel('disk', 2, 0);

for k = 1:length(fileNames)

      C(:,:,k) = im2bw(imread(fileNames(k).name));  

      C_filled(:,:,k) = imfill(imclose(C(:,:,k), se),'holes');

end
