The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Full-waveform topographic lidar : State-of-the-art (2009, background): “Based on a physical understanding of the pulse propagation and its interaction with the illuminated surface, Jutzi and Stilla (2006) propose a relevant algorithm to discriminate different surface responses which are very closely located in range ( 0.15m).”
Analysis of full-waveform LiDAR data for forestry applications: a review of investigations and methods (2011, methodology): “The entire signal can be smoothed to decrease the noise con tent using filters, such as the Weiner filter (Jutzi & Stilla 2006).”
Segmentation of tree regions using data of a full-waveform laser (2007, background): “Due to this approximation, specific features like temporal position, width and amplitude (cf. Figure 1) caused by the object surfaces are estimated (Jutzi & Stilla, 2006).”
Analysis of full waveform LIDAR data for the classification of deciduous and coniferous trees (2008, methodology): “Instead of approximating the measured waveforms, Jutzi and Stilla (2006) fit Gaussians to the surface response, which is obtained by measurement of the individual emitted waveform and a corresponding deconvolution of the received waveform.”
