Challenge @ECCV’2022: Concept drift in Object Detection applied to the largest annotated public thermal database

Challenge description: The challenge will use an extension of the LTD Dataset (Nikolov, Ivan Adriyanov, et al. "Seasons in Drift: A Long-Term Thermal Imaging Dataset for Studying Concept Drift." NeurIPS, 2021) which consists of thermal footage that spans multiple seasons. For deployment and long-term use of machine-learning algorithms in a surveillance context it is vital that the algorithm is robust to the concept drift that occurs as the conditions in the outdoor environment changes. This challenge aims to spotlight the problem of concept drift in a surveillance context and highlight the challenges and limitations of existing methods. It will be divided into three competition tracks. Depending on the track chosen the training data will vary, however the validation and testing data will remain the same across all challenges.

  1. Track 1 - Detection at day level: Train on a predefined and single day data and evaluate concept drift across time.

  2. Track 2 - Detection at week level: Train on a predefined and single week data and evaluate concept drift across time.

  3. Track 3 - Detection at month level: Train on a predefined and single month data and evaluate concept drift across time.
