There is an input image of a metal surface with lots of curves on it. I have used ' bwlabel ' function of MATLAB to identify all the curves of the image. Hence, each curve has its unique ID. Now my task is to connect two cruves which have gap between them. That is, there are two disjoint curves i.e. there is no connectivity between them, but I need to connect them and make them into a single curve.

E.g. In the above image, in the marked region, there are two disjoint curves which I would like to join.

Basically, I want a curve to be drawn joining those two curves.

Here is a larger image.

@KSSV

Can we use fillmissing to join two curves?

You can use imdilate to make the lines come closer to each other. This will increase the width of the lines as well. To reduce them back to their original, you can then use bwskel.

For more information of imdilate and bwskel, you can refer to the following links:
