A limitation of kNN methods is the lack of segmentation map describing where the anomaly lies inside the image. In this work we present a novel anomaly segmentation approach based on alignment between an anomalous image and a constant number of the similar normal images. Our method, Semantic Pyramid Anomaly Detection (SPADE) uses correspondences based on a multi-resolution feature pyramid. SPADE is shown to achieve state-of-the-art performance on u","authors_text":"Niv Cohen, Yedid Hoshen","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2020-05-05T17:43:35Z","title":"Sub-Image Anomaly Detection with Deep Pyramid Correspondences"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2005.02357","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9a4ee7593a7615f15731dc750a5279ce43f4cc925abd00937d709c6c14f202a5","target":"record","created_at":"2026-07-05T02:12:29Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"fff83acd250de4ce3576c1a3e42b29b582cbd07e5ef730bfad0a506f161759c4","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2020-05-05T17:43:35Z","title_canon_sha256":"4aaa6a9d592f75c631329908398bb57d981e391045f5265f4742fc4857dfe838"},"schema_version":"1.0","source":{"id":"2005.02357","kind":"arxiv","version":3}},"canonical_sha256":"0f5dfac76dd17e32d5935f22779160e007924f3730cdbee161198b83b39faf00","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0f5dfac76dd17e32d5935f22779160e007924f3730cdbee161198b83b39faf00","first_computed_at":"2026-07-05T02:12:29.400208Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:12:29.400208Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YyJQTRvTdPF4RVeI6m5uSxprhT5XlUu32XSiRTWC4mtItK6SRKPNXg3CpgAn5IU3IrDLWsitZnvlC/4TQwKpDw==","signature_status":"signed_v1","signed_at":"2026-07-05T02:12:29.400655Z","signed_message":"canonical_sha256_bytes"},"source_id":"2005.02357","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9a4ee7593a7615f15731dc750a5279ce43f4cc925abd00937d709c6c14f202a5","sha256:cf8fac5832a007b9d68626b07a156f0a6d6257830e1b4d1f590881a5182acc50"],"state_sha256":"313fa1db390be08952c88ecddaa93d0d23478ef861bbdb695a05f549851c2411"}
