Most commonly, this task is performed by thresholding a pixel-wise reconstruction error based on an $\\ell^p$ distance. This procedure, however, leads to large residuals whenever the reconstruction encompasses slight localization inaccuracies around edges. It also fails to reveal defective regions that have been visually altered when intensity values stay roughly consistent. We show that these problems prevent these approaches from being applied to complex real-world scenarios and that","authors_text":"Carsten Steger, David Sattlegger, Michael Fauser, Paul Bergmann, Sindy L\\\"owe","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-07-05T14:07:23Z","title":"Improving Unsupervised Defect Segmentation by Applying Structural Similarity to Autoencoders"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.02011","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":"sha256:07d49e8f48b5a43732ad3a72fd0464b18a3b372cd95af753d528e2b405b448b4","target":"record","created_at":"2026-05-17T23:49:17Z","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":"2d553c723ce9d919a691a160325ab2c0b445065b505ea145fa48f9ced05abcd7","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-07-05T14:07:23Z","title_canon_sha256":"bdbc3fbef4ed7f717515271f23dff3c3df518db5b625e606658f98c3233b47de"},"schema_version":"1.0","source":{"id":"1807.02011","kind":"arxiv","version":3}},"canonical_sha256":"227fe7abe7b8951b7d0d9d8c2f2444e6dc82d4626bfe0665ea7ea36a7d283426","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"227fe7abe7b8951b7d0d9d8c2f2444e6dc82d4626bfe0665ea7ea36a7d283426","first_computed_at":"2026-05-17T23:49:17.535819Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:49:17.535819Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qxHWfzyL8w6LXtf9jXuBBuOXLIPUtfbNYbII1MXuYVTdy0jpoalztknXH9pQHuGLJ4KT67s7n6n0N6h8+C21AA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:49:17.536272Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.02011","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:07d49e8f48b5a43732ad3a72fd0464b18a3b372cd95af753d528e2b405b448b4","sha256:5d9ec0d7ffd8e5956396140d34d0ac6cfe5c3641401ee8f51ab6aa235a75c4a2"],"state_sha256":"395b35490fb7b24b3ffcb409fb2cdf77cfacbd6f250aab32980e7f0897358741"}
