slclean

Removes small connected components from a streaming line file. Operates like a filter. slclean is designed to be used in piping mode (e.g. -islb -olsb).

Example usage:

slclean -i ../data/lidar_band10.slb -o ../data/lidar_band10_clean.slb

Removes all lines with a length shorter than 5 units.

slclean -i ../data/lidar_band10.slb -segment 100 -o ../data/lidar_band10_clean.slb

Removes all lines with fewer than 100 segments.

Also try:

slclean -i ../data/armadillo40.slb -oslb | sl_viewer.exe -islb
slclean -i ../data/armadillo40.slb -length 3 -oslb | sl_viewer.exe -islb
slclean -i ../data/lidar_band10.slb -length 2 -oslb | sl_viewer.exe -islb
slclean -i ../data/lidar_band10.slb -length 10 -oslb | sl_viewer.exe -islb
slclean -i ../data/lidar_band10.slb -length 10 -oslb | slsimp -islb -area 1 -oslb | sl_viewer.exe -islb

For more info:

slclean -h

Usage:

slclean -i in.slb -o out.slb
slclean -islb -osla -segment 50 < in.slb > out.sla
slclean -islb -osla -length 2.0 < in.slb > out.sla
slclean -compact -length 2.0 < in.slb > out.sla

The defaults are: -length=5.0 and -segment=0
