Hi Check this code,

clc

clear all;

close all;

%%

rgb=imread('im.jpeg');

gray=rgb2gray(rgb);

bw=im2bw(~gray,0.2);

clrb=imdilate(bw,strel('disk',2,4));

I=rgb(:,:,1);

BW=clrb;

[nbwl,cnt]=bwlabel(BW);

msk=zeros(2020,2020);

for i=1:cnt

fhls=find(nbwl==i);

msk(fhls)=i;

seg=label2rgb(msk);

st=i;

imwrite(seg,sprintf('%d.jpg',i))

imshow(seg)

pause(0.8);

drawnow()

end

Thank you for your answer. But I'm sorry for my imperfect question. I want to segment into lines and pads seperately.

[Selva Karna]

yes, you just convert binary image & segment holes [white pixel list]

Thank you! I got the segmented images (holes, lines and pads seperately). Thank you so much!!!
