Previous video-based methods require predefined object templates while single-image-based methods are template-free but lack temporal consistency. In this paper, we present a method to track human object interaction without any object shape templates. We decompose the 4D tracking problem into per-frame pose tracking and canonical shape optimization. We first apply a single-view reconstruction method to obtain temporally-inconsistent per-frame interaction recons","authors_text":"Gerard Pons-Moll, Jan Eric Lenssen, Xianghui Xie","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2024-08-25T22:26:46Z","title":"InterTrack: Tracking Human Object Interaction without Object Templates"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2408.13953","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":"sha256:7d4f23299f74f8553014f0c283a1c6b89906ae30f93e0deb5f3231bcac122d22","target":"record","created_at":"2026-07-05T08:59:14Z","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":"c0852a6f0f1e99706260aebf14a0e203b54e38fa01d9054fed63d4176ab80b02","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2024-08-25T22:26:46Z","title_canon_sha256":"df088959e3f35a56e01cb0074f99a6f787c774f5c0cec796aa9011d6481f5ed9"},"schema_version":"1.0","source":{"id":"2408.13953","kind":"arxiv","version":1}},"canonical_sha256":"7f59f0840213a688b5372eacc16a31c9bebbd54b642618540d4145f3bb5c2520","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7f59f0840213a688b5372eacc16a31c9bebbd54b642618540d4145f3bb5c2520","first_computed_at":"2026-07-05T08:59:14.089052Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:59:14.089052Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"huXmh0hLeToexgpB0NGIMYwAOgk+1NIpyfzw81qPUQLvAKl9Hvg5rbJkHE6hT2HlfpIJQlDCrplj2KTMJP1ZDA==","signature_status":"signed_v1","signed_at":"2026-07-05T08:59:14.089406Z","signed_message":"canonical_sha256_bytes"},"source_id":"2408.13953","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7d4f23299f74f8553014f0c283a1c6b89906ae30f93e0deb5f3231bcac122d22","sha256:d1faefcbf9de1e32ae1bfd9ceb2f2e0e9efbc1470fe39af13eb14aabc46509b2"],"state_sha256":"7343f4d30692bf8007b48f902d9a220e6687e9b32780e978b6f1da430ff83faf"}
