you may check GRASS 5.4, it contains the software from Prof Maria Brovelli,
Italy. See the src.contrib/POLIMICO/ directory.
Here the README details:
LIDAR data filtering
Command execution order:
s.bspline.reg/ : bilinear or bicubic spline interpolation Least quares approach
s.correction/ : DTM correction: error removal (building remainder, vegetation etc)
s.edgedetection/: detection of building edges, vegetation edges, etc.
s.growing/ : filling of previously computed edges
s.to.qrast/ : fast sites to raster conversion (replaces s.to.rast)
- GRASS Users conference 2002, Trento, Italy
- Brovelli, Maria A, Cannata, Massimiliano & Longoni, Ulisse M (2004)
LIDAR Data Filtering and DTM Interpolation Within GRASS.
Transactions in GIS 8 (2), 155-174.
Note that 5.4-CVS contains some updates which will appear in the
next 5.4.x release of GRASS.
Hope this helps
