From Offline to Periodic Adaptation for Pose-Based Shoplifting Detection in Real-world Retail Security
Shoplifting poses a significant operational and economic challenge for retailers, with incidents rising and substantial financial losses. Traditional video surveillance struggles with continuous human monitoring. This paper introduces a privacy-preserving, pose-based unsupervised video anomaly detection framework with periodic adaptation for real-world IoT deployment. Our approach enables edge devices to adapt from streaming, unlabeled data, providing scalable and low-latency anomaly detection across distributed camera networks, demonstrating superior performance and practical feasibility.

This research addresses the critical need for adaptive AI solutions in retail security, moving beyond static models to embrace dynamic, real-world IoT environments. By leveraging privacy-preserving pose-based anomaly detection with a novel periodic adaptation framework, enterprises can achieve significant improvements in theft detection accuracy and operational efficiency. The introduction of the RetailS dataset provides an unprecedented benchmark for training and evaluating models under realistic, multi-camera, multi-day conditions, bridging the gap between academic research and practical deployment.
Our framework introduces a three-stage pipeline for continual unsupervised shoplifting detection: filtering, collection, and training. This process is designed to enable edge devices in smart retail environments to adapt efficiently to streaming, unlabeled data. Filtering uses adaptive thresholds to pseudo-label normal frames, collection aggregates these into a buffered dataset, and training fine-tunes the model periodically.

The periodic adaptation framework consistently demonstrated superior performance, outperforming offline baselines in 91.6% of evaluations on AUC-ROC and AUC-PR metrics. This highlights its robustness against environmental and behavioral drift. The use of HPRS thresholds also proved more effective in controlling false alarms, a critical factor for operational viability in IoT deployments.
Core Performance Gain
91.6% Periodic Adaptation Outperforms Offline BaselinesThe RetailS dataset is a cornerstone of this research, offering a large-scale, multi-camera, pose-based collection of both staged and real-world shoplifting incidents. Unlike prior datasets, RetailS captures natural customer behavior and diverse concealment strategies across various camera views and spatial contexts, reflecting true IoT operational realities. This dataset is crucial for training models that can generalize effectively beyond biased, lab-staged scenarios.

Real-world Event Coverage
The RetailS dataset incorporates both authentic incidents spanning two years of IoT surveillance and systematically recorded staged scenarios to ensure comprehensive coverage of diverse concealment strategies and spatial contexts, reflecting true operational realities. This includes scenarios like hiding items in pants or hoodie pockets, and placing items in bags on the floor or while standing, providing robust training data against varied adversarial behaviors.
A key finding is the practical feasibility of our solution for real-world IoT deployments. Training updates consistently completed under 30 minutes on edge-grade hardware, specifically for lightweight models like SPARTA and STG-NF. This allows for frequent, half-day updates that effectively capture domain drift without compromising real-time inference stability at the edge. The decoupled edge inference and back-end adaptation approach ensures continuous operation and scalability.
