Greetings Martin Knoche:
Due to the small window between the end of the challenges and the paper due date, we have decided to extend paper submissions (along with supplemental PDF, movie demos, and code). 4th Recognizing Families In the Wild: An IEEE 2020 FG Challenge, all tracks, will be open for submissions until the end of the day on 1 February 2020 (time-zone, AoE).
We hope this helps and do let us know of any questions or requests.
Sincerely,
2020 RFIW Committee
