  The Diabetic Foot Ulcer Challenge 2022 focused on the task of diabetic foot
ulcer segmentation, based on the work completed in previous DFU challenges. The
challenge provided 4000 images of full-view foot ulcer images together with
corresponding delineation of ulcer regions. This paper provides an overview of
the challenge, a summary of the methods proposed by the challenge participants,
the results obtained from each technique, and a comparison of the challenge
results. The best-performing network was a modified HarDNet-MSEG, with a Dice
score of 0.7287.
