• 2019-02-14 The dataset is being prepared.
  • 2019-03-15 The dataset is released.
  • 2019-03-26 Dataet updated. The issue that one image in the training set cannot be read has been addressed.
  • 2019-05-12 New versions of evaluation tools online. Some bugs are fixed.
  • 2021-06-14 Please refer to [UG2+ Challenge] for the lastest progress.


DARK FACE dataset provides 6,000 real-world low light images captured during the nighttime, at teaching buildings, streets, bridges, overpasses, parks etc., all labeled with bounding boxes for of human face, as the main training and/or validation sets. We also provide 9,000 unlabeled low-light images collected from the same setting. Additionally, we provided a unique set of 789 paired low-light/normal-light images captured in controllable real lighting conditions (but unnecessarily containing faces), which can be used as parts of the training data at the participants' discretization. There will be a hold-out testing set of 4,000 low-light images, with human face bounding boxes annotated.
