Hello,

The seed must be manually extracted by selecting a small segment of the powerline with a LAS editor tool like CloudCompare. A seed of few meters shall be enough.
(Creating the seed with another algorithm could also work.)

I can send you a sample railway segment and a powerline seed to it, which was used to the get the results showcased in the README file. However for your own dataset you must create the seed for yourself.

Also, I have added the link to the master thesis behind the region growth algorithm to the end of the README in case you are interested in the details.
