Wrapper [exhaustive research and sequential feature selection (SFS)] and embedded [random forest (RF)] method results for three levels of information. (A) First level: images taken directly with RGB and MS cameras. (B) Second level: vegetation indices (VIs). (C) Third level: features derived from the 3D point cloud data. The red line in the SFS plots represents the number of selected features. Box plot and bar plot figures were created with the ggplot2 package in R version 4.1.1.28,29.
