| Nov 16, 2017 at 15:28 | comment | added | Jeffrey Evans | I have found that certain structural object geometries (eg., buildings) are identified quite well but morphological approaches perform quite poorly in forested areas, particularly with variable slopes. If the lidar data was acquired over a urban area I would certainly recommend MF but, other algorithms are much more effective given different physical settings. | |

Correct name of pipeline author. Remove coplanar filters from example pipeline as they are beside the point in this case. Fix JSON formatting to be uniform across examples.
