The Good, the Bad, and the Template: Contrastive Anomaly Detection in 3D
COSSAD-3D detects geometric defects in 3D point clouds by learning patch representations contrastively from sparse anomaly annotations, then comparing each test patch only against reference patches from the same location (ICPR 2026).
