OVERVIEW

We are excited to announce a new edition of the SkiTB Visual Tracking Challenge, part of the CV4WS workshop at WACV 2026. This challenge focuses on tracking skiers' performances across multiple camera views in complex, real-world winter sports environments. Participants will design trackers capable of following a skier throughout a performance, starting with the bounding box in the first frame and localizing the skier in all subsequent frames.
The challenge leverages the SkiTB dataset, featuring: 300 multi-camera professional skiing videos; 352,978 annotated frames; Full HD videos in dynamic, snowy outdoor environments. This dataset offers a unique opportunity to test tracking models on complex scenarios typical of winter sports.

The authors of the best perfoming methods will be invited to write a paper that describes the solution (max 8 pages + references in the WACV template), and to present their solution at the 4th Workshop on Computer Vision for Winter Sports at WACV 2026. The papers of the top submitters will be reviewed and, if accepted, will appear into the WACV 2026 workshop proceedings.



IMPORTANT DATES

November 17, 2025: challenge open
December 10, 2025: submission due
December 22, 2025: paper with solution's description due

Workshop date:

March 6 or 7, 2026
