Fig. 6

Comparison of the best and worst down-sampling strategies for qualitative segmentation results on the PlantNet network. The first and second rows show the semantic segmentation results and instance segmentation results, respectively, of three different samples using the 3DEPS strategy on PlantNet. The third and fourth rows show the semantic segmentation results and instance segmentation results, respectively, for the same three plant samples using the FPS down-sampling strategy on PlantNet. Each segmented crop point cloud is contrasted with its corresponding Ground Truth, and the red boxes are zoomed in areas for better visualization. Please note that for the instance segmentation, different colors are only used to distinguish between different adjacent leaf organ instances, and there is no correspondence between leaf color and leaf index
