Hello. I have extracted line segments using Hough's Transform. I would like to now determine the length of these lines, but I'm not sure how to do it. I have attached a picture of how the lines look now. Thank you.

I don't... Is there a way to automatically find the coordinates?

Surely. Can you post the image and the code?
You may be able to find the line segments by
H=get(gca, 'children')
Their coordinates should be in xdata and ydata properties
