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.


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

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

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