Learning deep feature correspondence for unsupervised anomaly detection and segmentation

作者:

Highlights:

• A learnable deep feature correspondence (DFC) method is proposed for unsupervised anomaly detection and segmentation.

• DFC achieves state of the art results on the benchmark unsupervised anomaly detection and segmentation task MVTec AD.

• DFC is very effective for detecting and segmenting the anomalous structures and patterns that appear in confined local regions of images, especially the industrial anomalies.

• The generality of DFC is demonstrated by applying it on a real industrial inspection scene.
