Imgs = dir(Directory);

for j=1:length(Imgs)

thisname = Imgs(j).name;

thisfile = fullfile(Directory, thisname);

try

Img = imread(thisfile); % try to read image

Im = rgb2gray(Img);

If2 = medfilt2(Im,[3 3]);

Bim=im2bw(If2);

I = bwmorph(Bim,'thicken',Inf);

figure

imshow(I)

title(thisname);

baseFileName= thisname;

fullFileName = fullfile('C:\Users\XXX\Desktop\Imges',baseFileName);

imwrite( I,fullFileName);
