Illustrative images of C. elegans on nematode growth medium (NGM) plates in challenging tracking scenarios: (A) interaction between 2 worms, (B) coiling with self occlusion of the worm contour, (C) high amplitude bending. Challenging scenes such as these are common occurrences during normal worm locomotion. Stable and accurate detection of worms at different maturation states through such scenarios is critical to achieve reliable and automated multi-worm tracking.
