The architecture integrates MobileNetv2 as a backbone for RGB feature extraction with a lightweight pyramid module (LPM) for depth processing, coupled with a cross-attention mechanism (CAM) for multimodal fusion and a spatial feature extractor (SFE) for enhanced structur","authors_text":"Guoqiang Huan, Jackie Alex","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-01-14T03:35:09Z","title":"LPCAN: Lightweight Pyramid Cross-Attention Network for Rail Surface Defect Detection Using RGB-D Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2601.09118","kind":"arxiv","version":2},"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":"sha256:165e2272a7e9325574e467054ccb2ec3b2b22ad10273c98bccefc8f20f66f713","target":"record","created_at":"2026-07-17T01:21:45Z","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":"331792c0246db579b886cd0279711304c2bf27a347bdc3bd65536d735c9e30ab","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-01-14T03:35:09Z","title_canon_sha256":"ad8c878d3aa04e1111ef521e465fb50cf1f0e8ad68304715782ac801a0b1b9fe"},"schema_version":"1.0","source":{"id":"2601.09118","kind":"arxiv","version":2}},"canonical_sha256":"a25fd2e7cbc99b72190dfc98919bfd353b69a81dfed303750e8e88ebab75b62c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a25fd2e7cbc99b72190dfc98919bfd353b69a81dfed303750e8e88ebab75b62c","first_computed_at":"2026-07-17T01:21:45.561421Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-17T01:21:45.561421Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"b2UML1Sp27pq4rvURkz4XGxb79kx02cCgkofgq+muSZZ0jJn1I3/AVPOEzxzKyM+k1OKiy8Jurkpj2ODBb7cDA==","signature_status":"signed_v1","signed_at":"2026-07-17T01:21:45.562311Z","signed_message":"canonical_sha256_bytes"},"source_id":"2601.09118","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:165e2272a7e9325574e467054ccb2ec3b2b22ad10273c98bccefc8f20f66f713","sha256:4e91800aad5d7c895f51e25e74bfc86d4e1fcd252e85ceef71395559b0bd9985"],"state_sha256":"b4131b3689443ea7b0812e5fbe7d35369476d3b8fd110dc15421ea03429b2e65"}
