Existing methods typically assume static scenes and/or multiple images with prior poses. Dynamics, sparse views, and unknown poses significantly increase the problem complexity due to insufficient geometric constraints. To overcome this challenge, we propose a method that can use only two images without prior poses to fit Gaussians in dynamic environments. To achieve this, we introduce two technical contributions. First, we propose an object-level two-view bundle adjustment. This strategy decomposes dynamic scenes into piec","authors_text":"Daniel Cremers, Haoang Li, Jiajie Chen, Shenhan Qian, Weihang Li, Weirong Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2024-12-01T15:25:33Z","title":"DynSUP: Dynamic Gaussian Splatting from An Unposed Image Pair"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.00851","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:e6d632ca987f4475f1704e8f462fb909adba120bcf4bb8adbf13afcb30258575","target":"record","created_at":"2026-07-05T09:42:49Z","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":"43fd29da12be885192ca7123a621987677fa9a49d329de6cf43293f74c0c4977","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2024-12-01T15:25:33Z","title_canon_sha256":"b0037c49d96b6e53907347956ca58c25d770ccfa61b3d7af77ad6d7ba7cff410"},"schema_version":"1.0","source":{"id":"2412.00851","kind":"arxiv","version":1}},"canonical_sha256":"70bed13edbc503b019fa9c2709c7212056b38f81618c3f2d164d432d229900f6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"70bed13edbc503b019fa9c2709c7212056b38f81618c3f2d164d432d229900f6","first_computed_at":"2026-07-05T09:42:49.305662Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:42:49.305662Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ee05192z8f7UOc9s62F5MLPi96Ilp5pSJlXgrYhpFggyf0/w1hdo2MX0CHQDT10Zk1PD/ZnhCgnZkEZxaf+CAg==","signature_status":"signed_v1","signed_at":"2026-07-05T09:42:49.306293Z","signed_message":"canonical_sha256_bytes"},"source_id":"2412.00851","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e6d632ca987f4475f1704e8f462fb909adba120bcf4bb8adbf13afcb30258575","sha256:8ca4941b1cb4f2251bc3a09494f294b24b447689794399d3a583f559740da1cd"],"state_sha256":"e85c77a090651483980891af655548bf6b42470ef300da9475507cfd4b2b4261"}
