First, we conduct a pilot study based on a 1D signal and relate our findings to 3D scenarios, where the naive joint pose optimization on voxel-based NeRFs can easily lead to sub-optimal solutions. Moreover, based on the analysis of the frequency spectrum, we propose to apply convolutional Gaussian filters on 2D and 3D radiance fields for a coarse-to-fine training schedule that enables joint camera pose optimization","authors_text":"Bo-Yu Cheng, Wei-Chen Chiu, Yu-Lun Liu","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2024-02-20T18:59:02Z","title":"Improving Robustness for Joint Optimization of Camera Poses and Decomposed Low-Rank Tensorial Radiance Fields"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2402.13252","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":"sha256:0e6305c9b2530d11561820c7d9fd081ec95c0cd02b9cce733ef101ed50727e78","target":"record","created_at":"2026-07-05T07:47:22Z","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":"32549025e1cc667618eab293391352b259c58c97a6ba0266afe14af2271711a8","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2024-02-20T18:59:02Z","title_canon_sha256":"26dbca9833d8102569784030e70de3b0700c353ba193c1476aa460f5f27fa0d7"},"schema_version":"1.0","source":{"id":"2402.13252","kind":"arxiv","version":1}},"canonical_sha256":"292e791321e133c451dde7c3700e47495154b5db44900af24d5ac2428a2b845c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"292e791321e133c451dde7c3700e47495154b5db44900af24d5ac2428a2b845c","first_computed_at":"2026-07-05T07:47:22.550601Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:47:22.550601Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"y/S8ShgZE6LUwBZmyyWPn/aavTIaPVme6v026PxYaIiXsOha+5W2jAN5gtg/aYaEsox8cW44K1sbu+79m8qCDg==","signature_status":"signed_v1","signed_at":"2026-07-05T07:47:22.551089Z","signed_message":"canonical_sha256_bytes"},"source_id":"2402.13252","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0e6305c9b2530d11561820c7d9fd081ec95c0cd02b9cce733ef101ed50727e78","sha256:bf9882b6bbfcc692e47aa8046f0ec185fb7b3a3c8c3b714d2a9f4e6e7fd39a76"],"state_sha256":"fc26852d7fd4fa94ad7a138645b29e1368b5ce3b78f8da2decc262356c153e9c"}
