Highlights💴

• 509 unique identities | 13M+ bounding box annotations | 7 international collection sites
• 18 UAV viewpoints per subject — altitudes 5m to 120m, distances 10m to 120m, pitch angles 30°/60°/90°
• Clothing variation across sessions — tests long-term identity persistence
• 16 soft biometric attributes per frame — demographics, appearance, clothing, action
• 4 tasks: Person Detection · Re-ID · Multi-View Tracking · Action Recognition
