A Fuzzy Mean-Shift Approach to Lidar Waveform Decomposition

, 2016
Waveform 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 ...

A fast Maximum Likelihood method for improving AMCW lidar precision using waveform shape [PDF]

, 2009
Amplitude Modulated Continuous Wave imaging lidar systems use the time-of-flight principle to determine the range to objects in a scene. Typical systems use modulated illumination of a scene and a modulated sensor or image intensifier.
