[Specker, Andreas]

Dear colleagues,

We invite you to participate in the UPAR Challenge 2027, organized in conjunction with the Real-World Surveillance (RWS) Workshop at WACV 2027.

The challenge focuses on human-centric understanding in real-world surveillance and comprises three tracks:

  1.  Pedestrian Attribute Recognition (PAR) Recognition of pedestrian attributes under challenging domain shifts.
  2.  Attribute-Based Person Retrieval (ABPR) Retrieval of pedestrians using semantic attribute descriptions across datasets and surveillance domains.
  3.  Human Pose Estimation (HPE) Estimation of human body keypoints under variations in viewpoint, resolution, illumination, and occlusion.

Important dates (AoE):
