Starting with the 3-dimensional habitat reconstruction data (A), we used a ground the classification algorithm MCC-LIDAR to identify non-ground points (B). We then rasterized these data to a grid with 20 × 20 cm pixels (C). Here, black pixels indicate ground and white pixels indicate non-ground. Using image segmentation, we identified connected clusters of pixels (D), here represented as sections of different colors (with the ground here represented in blue). We then removed all identified objects smaller than 2 m2 to reduce small-scale noise (E). (F) shows the baboon trajectories (in red) overlaid on the processed image.
