Dear comunity,
I have the following image composed by many (almost closed) lines. I am contacting you because I would like to know if somebody has an elegant solution to connect the lines (some of them are broken). If possible, I would like to avoid the use of morphological operators as it is importat to me to maintain the lines profile.
Thank you in advance for your help,
Santiago

Dear Mohammad Sami,
That sounds very interesting. Could you please explain a little bit more? (e.g. how to plot the lines...)
Thank you very much.

Have you looked at the documentation for the houghlines function? It includes an example.
As for my suggestion, you can very easily create a non-symmetrical structuring element like this:
r=1;
x=linspace(-1,1,10);
y=linspace(-2,2,10);
[X,Y]=ndgrid(x,y);
SE=sqrt(X.^2+Y.^2) <= r;
