We develop a foundational probabilistic model for EC event detection, grounded in photon statistics, that unifies the description of static scene noise events and step response curves (S-curves) within a single analytical framework. Three formulations of the probability distributions are derived, spanning all intensity regimes: exact Poisson, saddle-point, and Gaussian. The model reveals the underlying connection between these otherwise disparate EC behaviors and clarifies the interpret","authors_text":"Julinda Mujo, Min Xu, Owen Root","cross_cats":["physics.optics"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-05-04T21:34:46Z","title":"Noise2Params: Unification and Parameter Determination from Noise via a Probabilistic Event Camera Model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.16317","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":"sha256:1928001000ed4dc91374e55f16d6e947d30aa2808e2c39d7d1fcd17b00babde7","target":"record","created_at":"2026-05-20T00:02:16Z","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":"a0880e83051536ef22a7ba1bc5d7b25d8ba0d977066d2f7c7e35ad3dc5ac2969","cross_cats_sorted":["physics.optics"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-05-04T21:34:46Z","title_canon_sha256":"872b86b7d3dff1378b9d842753b22be95f09b08c57bb6178be38298ae8594db4"},"schema_version":"1.0","source":{"id":"2605.16317","kind":"arxiv","version":1}},"canonical_sha256":"2089758b97543f2bfc889b74ab9c85c4710f70091321214636b691269f2ec77a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2089758b97543f2bfc889b74ab9c85c4710f70091321214636b691269f2ec77a","first_computed_at":"2026-05-20T00:02:16.671661Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T00:02:16.671661Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"m1xfLQA8r03J4oDkKd43lcjFESNRBj9sbUjIzS2flFEwt70GYuH/rpU6bnElVgKtpPVDLbp9SoVx+EmQnF4gBA==","signature_status":"signed_v1","signed_at":"2026-05-20T00:02:16.672306Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.16317","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1928001000ed4dc91374e55f16d6e947d30aa2808e2c39d7d1fcd17b00babde7","sha256:6fb8b7aa788d2fc360fd659a63d9a5f7eaf3e0e0d15eaafec71fe3c32103cf9a"],"state_sha256":"ec2496a4fb5e453c1e10d7b4a53cba59bb713465f99a2408c313e3748923e940"}
