I am not getting the thin image please solve this problem.

function img = loading
imagefolder='C:\Users\Dell\Desktop\python tutorials\matlab\myfiles\matlab\myfiles\Dataset 1';
fileextension='.tif';
img=cell(1);
foldercontent=dir([imagefolder,'*',fileextension]); % loads images in foldercontent variable.
n=size(foldercontent,1);
[filename, pathname] = uigetfile('*.tif', 'Pick an Image');
        if isequal(filename,0) || isequal(pathname,0)
        warndlg('Image is not selected');
        else
        a=imread(fullfile(pathname,filename));
              imshow(a); 
        end
tic        
for i=1:n
    disp(i);
    string = [imagefolder,foldercontent(i,1).name];
    image =imread(string);    
    img{i,1}=string;
    img{i,2}=image;

binary_image1=im2bw(img{i,2});
%Small region is taken to show output clear
binary_image = binary_image1(20:100,20:150);
figure;imshow(binary_image);title('Binary image');

%Thinning
thin_image=~bwmorph(binary_image,'thin',Inf);
figure;imshow(thin_image);title('Thinned Image');

sir please tell me where is the wrong in the above code

add a slash at the end of imagefolder because currently you are looking at

imagefolder='C:\Users\Dell\Desktop\python tutorials\matlab\myfiles\matlab\myfiles\Dataset 1';
fileextension='.tif';

Type in coomand window

dir([imagefolder,'*',fileextension])

No matches for pattern 'C:\Users\Dell\Desktop\python tutorials\matlab\myfiles\matlab\myfiles\Dataset 1*.tif'.

and foldercontent will be empty

Now add a slash at the end of imagefolder

imagefolder='C:\Users\Dell\Desktop\python tutorials\matlab\myfiles\matlab\myfiles\Dataset 1\';
fileextension='.tif';

Now type in command window

dir([imagefolder,'*',fileextension])

foldercontent was empty when you gave it wrong path, now it has all the files *.tif

Thank you for your response. I'm getting a single line in the thinning image . I just need the thinning images so that i can extract the minutiea points.

[Mehmed Saad]

like in a variable?

[uma]

yes

[Mehmed Saad]

you are storing all the images in img cell array, go for a similar approach

i dont want to be rude but is this your own code?

[uma]

thanks for the reply.

Yes i have written this code myself.
