Does regular lmf works as usual ?
Yes
# finished in about 5 minutes
ttops <- find_trees(las, lmf(ws = 2))
Local maximum filter: [==================================================] 100% (4 threads)
# after 10 minutes...
> ttops <- find_trees(las, lmfauto())
Local maximum filter: [--------------------------------------------------] 1% (4 threads)s)
Maybe what is happening is a large ws
is being selected?
I have a lot of stuff to deal with these days. I'll try to investigate within a week.
I was playing with lmfauto() and have a file where it takes about 45 minutes to complete find_trees on a 32 core machine, sharing in case it's useful, if not feel free to ignore.
