To complement the lack of 3D information, depth-based models, such as DSNeRF and MonoSDF, explicitly assume the availability of accurate depth maps of multiple views. They linearly scale the accurate depth maps as supervision to guide the predicted depth of few-shot NeRFs. However, accurate depth maps are difficult and expensive to capture due to wide-range depth distances in the wild.\n  In this work, we present a new Sparse-view NeRF (SparseNeRF) framework that exploits depth priors from rea","authors_text":"Chen Change Loy, Guangcong Wang, Zhaoxi Chen, Ziwei Liu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2023-03-28T17:58:05Z","title":"SparseNeRF: Distilling Depth Ranking for Few-shot Novel View Synthesis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2303.16196","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":"sha256:7ab1928c6b898d7669a2aeba552c186f6f371af236fff3e823a9d8890d277a93","target":"record","created_at":"2026-07-05T06:40:32Z","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":"03a4c19bb8788f7b6c4ad09f1ad5636e8116ce820f0fdf6d8245d94ee61f945d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2023-03-28T17:58:05Z","title_canon_sha256":"c7e5147c5c2bce32270f224dd366ecee4a51c1e630c36cb9bbb032c5ee19c726"},"schema_version":"1.0","source":{"id":"2303.16196","kind":"arxiv","version":2}},"canonical_sha256":"12f7911e943efa14ea1a77ba4a6aa2f5d9a0e5da9d1f4e16fe2fb5be4a7f2c86","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"12f7911e943efa14ea1a77ba4a6aa2f5d9a0e5da9d1f4e16fe2fb5be4a7f2c86","first_computed_at":"2026-07-05T06:40:32.950256Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:40:32.950256Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8DqLmFuxlhxH2D/2/txe+5Z1ExX49KQvkZ0t/J7yzEm58Q73LLRGOoMa5EbjPvGOOrhA/GB2ZTEOiZiNAd1bDw==","signature_status":"signed_v1","signed_at":"2026-07-05T06:40:32.950734Z","signed_message":"canonical_sha256_bytes"},"source_id":"2303.16196","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7ab1928c6b898d7669a2aeba552c186f6f371af236fff3e823a9d8890d277a93","sha256:884e25265b2acc90b8c4d70f861f9a0e06fbaad953b033c722d579f5f55b09a6"],"state_sha256":"09c84abc7019c55538d8391223c679bac7ecfdfaa607dfe4b143c9e4a1dd6d97"}
