However, they sometimes fall short because of the unaccounted defect patterns or over-sensitivity about some hyper-parameters. In this work, we design a deep model that accurately detects PCB defects from an input pair of a detect-free template and a defective tested image. A novel group pyramid pooling module is proposed to efficiently extract features of a large range of resolutions, which are merged by group to predict PCB defect of corresponding sca","authors_text":"Fan He, Jie Yang, Sanli Tang, Xiaolin Huang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2019-02-17T03:39:24Z","title":"Online PCB Defect Detector On A New PCB Defect Dataset"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.06197","kind":"arxiv","version":1},"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:a72738ad9bc368bf337f63910d25b097ab199b5e20dfb3dc4ad5aa1a3eab764e","target":"record","created_at":"2026-05-17T23:53:46Z","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":"c6cef0b331db11b21052ce9bad205f2fc8489a0be7a2d2074d7a3b0056d174b3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2019-02-17T03:39:24Z","title_canon_sha256":"510effa0e920db2de858916950c4cbeec6a6086ca5ce662527aae91e1fcbe565"},"schema_version":"1.0","source":{"id":"1902.06197","kind":"arxiv","version":1}},"canonical_sha256":"289d76ec58d15eed1c37e4b8942c854cb6f2fc8050b7d72620312d30d6271c95","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"289d76ec58d15eed1c37e4b8942c854cb6f2fc8050b7d72620312d30d6271c95","first_computed_at":"2026-05-17T23:53:46.303882Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:53:46.303882Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5lIQTG2VEeL2uU5V1c5vIMpmUb+m3Tu4C6hdEB9gJjKYHzKavp5RQghL8z8Ry2e4HEXA053HQSOPtn3i39ZxDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:53:46.304381Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.06197","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a72738ad9bc368bf337f63910d25b097ab199b5e20dfb3dc4ad5aa1a3eab764e","sha256:368a88e570f96ca6f31a591d90efe5a4443e00d830b9fbfd823d738be3481217"],"state_sha256":"387cd6a672c9a238911d9cf2d74b669157286fd56c119b46e61e2dc6a315180a"}
