I don't understand the question. The output from my command is:

You want to remove some lines from the output. What rules determine which lines are to be removed?

[mmmaks2004]

maybe so,
Rules:
1. Find points that form a junction of 3 lines
3. Remove the shortest line (from 3 lines), if the length is less than 10 pixels


Is it possible to reduce the thickness of the lines of letters to 1 pixel?

See the morphology page I linked to.

Each line has two or more line-ends (except for loops), and zero or more junctions. The lines can be broken at junctions into segments. We can forget about segments that don't have a line-end. "-connected-components" tells us the size of each segment, so we can remove all segments that are smaller than a certain size.

When we have found segments, I can't see how to easily identify which segments have a common junction.
