Figure 6.

Montage of eight images of a bean basal root. The images are at 90-min intervals from a sequence of 72 images originally captured at 5-min intervals. The images on the left show the patterns on the root generated by graphite particles, whereas the images on the right show the tracked marker points and the root edges on the same images of the left. The upper and lower edges of the growing root are detected by KineRoot, and the bold white line shows the root midline. The black dots show the tracked points.
