A Fuzzy Mean-Shift Approach to Lidar Waveform Decomposition
IEEE Transactions on Geoscience and Remote Sensing, 2016Waveform decomposition is a common step for exploitation of full-waveform lidar data. Much effort has been focused on designing algorithms based on the assumption that the returned waveforms follow a Gaussian mixture model where each component is a Gaussian.

Gaussian Decomposition of LiDAR Waveform Data Simulated by Dart
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018Light Detection And Ranging (LiDAR) techniques have been extensively applied in spaceborne, airborne and ground-based platforms. Understanding LiDAR data requires modeling approaches that can precisely account for the physical interactions between the emitted laser pulse and reflecting targets.

Fast Surface Detection in Single-Photon Lidar Waveforms
2019 27th European Signal Processing Conference (EUSIPCO), 2019Single-photon light detection and ranging (Lidar) devices can be used to obtain range and reflectivity information from 3D scenes. However, reconstructing the 3D surfaces from the raw waveforms can be very challenging, in particular when the number of spurious background detections is large compared to the number of signal detections.

Effects of clumping on modelling LiDAR waveforms in forest canopies
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Empirical relations are frequently used to derive leaf area index (LAI). Such relations often make assumptions that make it hard to link the derived LAI to realistic trees and forest canopies. In previous work we developed a set of analytical expressions to describe LiDAR waveforms with only a limited number of assumptions based on radiative transfer ...

A Wavelet-Based Echo Detector for Waveform LiDAR Data
IEEE Transactions on Geoscience and Remote Sensing, 2016This paper presents a wavelet-based (WB) echo detector that can recover the echoes missed by a light detection and ranging (LiDAR) system via on-the-fly detection. An on-the-fly detection method normally utilizes a simple threshold (TH) to register a target point.

Simulating full-waveform LIDAR
2012LIDAR (LIght Detection And Ranging) is used to remotely measure the threedimensional shapes and arrangements of objects with high efficiency and accuracy by making precise measurements of time-of-flight of pulses of light. Discrete return LIDAR systems provide a discrete series of elevation points corresponding to reflections from objects in the scene.
