However, most of the existing models predict incorrect, lifeless 3d estimates, that miss the subtle human contact aspects--the essence of the event--and are of little use for detailed behavioral understanding. This paper addresses such issues with several contributions: (1) we introduce models for interaction signature estimation (ISP) encompassing contact detection, segmentation, and 3d contact signature prediction; (2) we show how such components can be leveraged to ensure contact con","authors_text":"Alin-Ionut Popa, Cristian Sminchisescu, Elisabeta Oneata, Mihai Fieraru, Mihai Zanfir, Vlad Olaru","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2023-08-03T16:20:33Z","title":"Reconstructing Three-Dimensional Models of Interacting Humans"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2308.01854","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":"sha256:560fa7086f6d6b7da594989a7d63a3faeb4fac5699b967ff551f19a90cbc9fd1","target":"record","created_at":"2026-07-05T06:37:34Z","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":"706864b97a8b1cc1887ede0f9c619aff595069e0ca07f622331fa05d8e239bef","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2023-08-03T16:20:33Z","title_canon_sha256":"5abca660bddd61048b0739ddc9b3f36bcd5cdfa9de63db48c3eaf06d444e971d"},"schema_version":"1.0","source":{"id":"2308.01854","kind":"arxiv","version":2}},"canonical_sha256":"40e7d2c858cf396255ed00de47a4ef7defd0c9729618ca5c218a2ddfb12d8606","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"40e7d2c858cf396255ed00de47a4ef7defd0c9729618ca5c218a2ddfb12d8606","first_computed_at":"2026-07-05T06:37:34.828096Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:37:34.828096Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gDSvYmGbEIuyAJ8XnVBRqHmOMBuXXOVmmGit/AX2sPgBHJx3MmlGMIq3jq/pEPoJuEG+NyIQCiLRvzaP0+/6Bw==","signature_status":"signed_v1","signed_at":"2026-07-05T06:37:34.828575Z","signed_message":"canonical_sha256_bytes"},"source_id":"2308.01854","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:560fa7086f6d6b7da594989a7d63a3faeb4fac5699b967ff551f19a90cbc9fd1","sha256:f9020612ac9c8fab5ff83bdf27cb5dbd47da58e24f6afdda9641f11a5144cdfe"],"state_sha256":"8106fb00f7294e7ce34c2a1a61d356c787f7a579f58b7422f0f668f696d52f81"}
