Towards Total Recall in Industrial Anomaly Detection

🤖 Plain-English Summary

Being able to spot defective parts is a critical component in large-scale industrial manufacturing. We further report competitive results on two additional datasets and also find competitive results in the few samples regime.

🔑 Key Findings

• A particular challenge that we address in this work is the cold-start problem: fit a model using nominal (non-defective) example images only.
• While handcrafted solutions per class are possible, the goal is to build systems that work well simultaneously on many different tasks automatically.
• The best peforming approaches combine embeddings from ImageNet models with an outlier detection model.
