“…For example, augmenting the density of laser pulse footprints increases the chance of the laser sampling the "true" treetop, irrespective of whether the approaches are based on a raster DSM or the point cloud (Chen et al, 2006;Lefsky et al, 2002;Li et al, 2012;White et al, 2016). To reduce omission and commission errors, an efficient local maxima technique is required -in others words, an appropriate window size for the particular crown sizeenhances treetop detection by reducing omission and commission errors (Kathuria et al, 2016;Wulder et al, 2000). However, a major shortcoming of treetop detection approaches is that accuracy is largely dependent upon the structural complexity of forest structure (Falkowski et al, 2008).…”
