LACToS: Local Anomaly Detection via Conditional Typicality of Superpixels

This work proposes LACToS, a principled local OOD detection method based on statistical typicality and made tractable through two innovations: (i) grouping pixels into superpixels and (ii) using a computationally efficient proxy to estimate typicality.
