Fig. 8

Segmentation of a voxel grid representation of a tomato seedling in stem (green) and individual leaves (colored) (left), and schematic illustration of the stem-leaf segmentation algorithm (right), as used by [101]. The structure is filled from the bottom (red point). As long as neighboring points are close together in space, they are treated as stem. Once they spread out, the end of the stem (yellow points) is marked. The last point additions correspond to leaftips (green and blue points).
