How can I connect my connected-components?

This is a part of my binary image, and I got it by command "skel= bwmorph(BW,'skel',Inf)" .

I want to connect these white connected components, mergeing them into one connected component.

How can I do it?

THANKS! :)

I = imread('QQ20190319105427.png') ;
I1 = rgb2gray(I) ; 
imshow(I)
hold on
[c,h] = contour(I1) ;

Thanks, KSSV.

I am sorry, I cannot figure out your code.

My connected components were not merged into one component.

DRawing the contours....you will get your coordinates.....you want to join all the white lines?

Yes! I want to join all the white lines.
