Observation Selection, Total Variation, and L-Curve Methods for LiDAR Data Denoising

Algorithm 2

L-curve Method.

	Input: The set of parameters values , , .
	Initialization: Corner point
(1)	while the set of parameter values is not empty do
(2)	Select (, ) from the parameter set
(3)	Find the corner point of the generated lines of points from a set of values, and record the corresponding .
(4)	If the position of is higher than the position of in the D-S plot, set , , ,
(5)	end while
