CONTINUAL VISUAL ANOMALY DETECTION ON THE EDGE: BENCHMARK AND EFFICIENT SOLUTIONS
Visual Anomaly Detection (VAD) is crucial for industrial inspection and healthcare. This research tackles the dual challenge of deploying VAD models on computationally constrained edge devices while enabling them to adapt continually to evolving data distributions without forgetting previous knowledge. We present the first comprehensive benchmark for this combined scenario and introduce efficient solutions.
Our findings reveal significant advancements: Tiny-Dinomaly, a lightweight adaptation of the Dinomaly model, achieves a 13x smaller memory footprint and 20x lower computational cost while improving Pixel F1 by 5 percentage points. We also introduce targeted modifications to PatchCore and PaDiM that enhance their efficiency and suitability for continual learning on edge devices. This work provides critical guidance for selecting optimal VAD methods and backbones under joint efficiency and adaptability constraints.

Adapting to Evolving Data in Real-time
Conventional VAD solutions struggle with evolving data distributions and resource constraints of edge devices. This research establishes a benchmark to evaluate VAD models under these combined challenges, demonstrating that models must adapt to new object categories sequentially without catastrophic forgetting, all while operating within strict memory and computational budgets.
Next-Generation Anomaly Detection for Edge
Our novel Tiny-Dinomaly model, built on the DeiT-Tiny backbone, represents a significant leap forward for edge VAD. It delivers state-of-the-art pixel-level anomaly localization with a 13x smaller memory footprint and 20x lower computational cost compared to its larger counterpart, Dinomaly with ViT Base. This efficiency is achieved while improving Pixel F1 by 5 percentage points, showcasing how structural regularization from a compact encoder can outperform explicit architectural constraints for larger models.
Efficient Memory Management for Continual Learning
We've introduced targeted modifications to classic memory-bank and distribution-based VAD methods like PatchCore and PaDiM. PatchCoreCL++ reduces inference costs by 12x through prototype-based task identification and improves Pixel F1 by 2.3 percentage points. Our corrected PaDiM-CL UniModal significantly improves Pixel F1 by over 35 percentage points compared to the original formulation, and PaDiM-CL-Lite MultiModal offers a compelling trade-off, balancing accuracy and memory efficiency suitable for edge deployment.
