We investigate completion through continuous-time generative modeling and introduce PCFM, a PTv3-backed flow matching approach for medical point cloud completion. We evaluate on SkullFix and SkullBreak, and additionally on the more recent Mandibular Defect dataset. We build strong baselines by adapting PTv3 to a deterministic encoder-decoder completion model and by instantiating diffusion completion (PCDiff) with bo","authors_text":"Kamil Kwarciak, Marek Wodzinski","cross_cats":["cs.AI","cs.LG"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2026-06-23T11:09:20Z","title":"MedPCFM: Improving Medical Point Cloud Completion by Integrating Point Transformers and Flow Matching"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.24433","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:ea79c4d0b8b41e8feefb11793c21ed9956d6b31fe7a38e88b7387077dc4b156e","target":"record","created_at":"2026-06-24T01:15:30Z","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":"7bc6b22fd55797d29d4626e6f830b0e441f2c145bbbc3c7b5b7ccb98d8b9f664","cross_cats_sorted":["cs.AI","cs.LG"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2026-06-23T11:09:20Z","title_canon_sha256":"a0916c5015953ee5050ef4485fab4ebf9370d637fa84711f29ab1b06d351d8ac"},"schema_version":"1.0","source":{"id":"2606.24433","kind":"arxiv","version":1}},"canonical_sha256":"54c3691d4f6369fbf6d9fed4f1d441ea4e79ccc2f17f8000f3ca11da2a7d37b5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"54c3691d4f6369fbf6d9fed4f1d441ea4e79ccc2f17f8000f3ca11da2a7d37b5","first_computed_at":"2026-06-24T01:15:30.260045Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-24T01:15:30.260045Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ib6wltoRcBvus4wEH7hghYYMzDiRES1XjFKWSbnkA/1M4k7CWE7g384YRqqBtHyVCRGZeOvPL5UY4dmkOa/gAw==","signature_status":"signed_v1","signed_at":"2026-06-24T01:15:30.260421Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.24433","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ea79c4d0b8b41e8feefb11793c21ed9956d6b31fe7a38e88b7387077dc4b156e","sha256:73de4ce6dd59c1bac5bd0ff8c5c96b139cf9da4d30da0f26489abdfb371f8d75"],"state_sha256":"8c8e39883b6101bafa1ff3830c290057005300bb3edc056d27b2f85c6a10ed46"}
