Trends in Automatic Individual Tree Crown Detection and Delineation - Evolution of LiDAR Data (2016, methodology): “Popescu and Zhao [76] developed a voxel-based method to estimate crown base height after using local maximum focal filtering from a CHM for ITCD.”
Estimation of tree crown volume from airborne lidar data using computational geometry (2013, methodology): “Techniques based on for example, the use of voxels (Popescu and Zhao 2008), alpha shapes (Vauhkonen et al. 2008), and level set functions (Tang, Dong, and Buckles 2013) have been proposed for this purpose.”
Three-dimensional surface reconstruction of tree canopy from lidar point clouds using a region-based level set method (2013, background): “Forest growth, competition, and biomass are directly correlated with tree height, canopy area, and volume (Lim et al. 2003; Meng, Lieffers, and Huang 2007; Popescu and Zhao 2008; Van Leeuwen, Coops, and Wulder 2010).”
Estimating crown base height for Scots pine by means of the 3D geometry of airborne laser scanning data (2010, methodology): “The present results, in common with those of Popescu and Zhao (2008), show that it is possible to obtain accurate CBH estimates with modest pulse densities.”
Capturing tree crown formation through implicit surface reconstruction using airborne lidar data (2009, methodology): “trees. Alternatively, a median filter was applied to the vertical lidar point distribution (Holmgren & Persson, 2004) to get an R2 of 0.71, while a voxel-based method ( Popescu & Zhao, 2007 ) yielded R2 values”
Predicting Tree Attributes and Quality Characteristics of Scots Pine Using Airborne Laser Scanning Data (2009, methodology): “When the present results are compared with those of earlier crown height studies based on laser scanning (Naesset and Okland 2002, Holmgren and Persson 2004, Maltamo et al. 2006a, Popescu and Zhao 2008 ), the results of the current study seem to be more accurate.”
Comparison of small-footprint discrete return and full waveform airborne lidar data for estimating multiple forest variables (2016, methodology): “There exists a number of alternative 578 methods which could be implemented in future research, such as the detection of vertical 579 layers by examining the return frequencies at different binned heights (or voxels) above 580 ground (e.g. Popescu & Zhao 2008; Wang et al., 2008).”
