Computer motion analysis was tested as an ultra‐sensitive imaging technique to detect minute displacement of corn seedling growth. The motion analysis software displayed motion in vector form, i.e. as both magnitude and direction of seedling elongation. The system was able to detect increments of growth in a non‐intrusive, non‐contact fashion as minuscule as 5 microns.
