Challenge Dataset

We  have  received  approval  from  the  UK  National  Health  Service  (NHS)  Re-search Ethics Committee (REC) to use these images for the purpose of research. The NHS REC reference number is 15/NW/0539. Foot images with DFU were collected from the Lancashire Teaching Hospital over the past few years. Three cameras were used for capturing the foot images, Kodak DX4530, Nikon D3300and Nikon COOLPIX P100. The images were acquired with close-ups of the full foot at a distance of around 30–40 cm with the parallel orientation to the plane of an ulcer. The use of flash as the primary light source was avoided, and instead, adequate room lights were used to get the consistent colours in images. Images were acquired by a podiatrist and a consultant physician with specialization in the diabetic foot, both with more than 5 years professional experience. As a pre-processing stage, we have discarded photographs with out of focus and blurry artefacts.

The  dataset  for  DFUC2020  consists  of  2000  images  available  for  training and  200  images  for  validation.  Additionally,  the  test  dataset  (planned  release 01/07/2020) will contain an additional 2000 images, comprising images of DFU and other foot conditions. A case refers to one foot image. All training, validation and test cases are annotated with the location of foot ulcers in xmin, ymin, xmax and ymax coordinates.
