📝 Overview

ANUBIS is a large-scale skeleton-based action recognition dataset designed to address critical gaps in existing benchmarks. The dataset features 102 action categories collected from 80 participants across 80 viewpoints, generating 66,232 skeleton clips with comprehensive multi-modal data (RGB, Depth, 3D Skeleton).

Key Innovations

• 🎯 Multi-View Coverage: 80 viewpoints including challenging back-view perspectives often missing in existing datasets
• 👥 Multi-Person Interactions: Complex social interactions including collaborative and aggressive behaviors
• 🔍 Fine-Grained Actions: Detailed hand/object manipulations and contemporary social behaviors
• ⚔️ Security-Critical Actions: Violent and aggressive actions essential for surveillance applications
• 🦠 Modern Social Behaviors: Pandemic-era gestures and social distancing protocols

🎯 Key Challenges

1. Viewpoint Variation: Back-view perspectives with joint occlusions
2. Fine-Grained Recognition: Subtle hand gestures and object manipulations
3. Multi-Person Dynamics: Complex interpersonal interactions
4. Action Similarity: Semantically similar actions with different contexts
5. Motion Complexity: Varying temporal scales and movement patterns
