Most existing methods directly extract video-based rPPG features by designing neural networks for heart rate estimation. Although they can achieve acceptable results, the recovery of rPPG signal faces intractable challenges when interference from real-world scenarios takes place on facial video. Specifically, facial videos are inevitably affected by non-physiological factors (e.g., camera device noise, defocus, and motion blur), leading ","authors_text":"Guoying Zhao, Jingang Shi, Menghan Xia, Mengyao Yuan, Shuyang Chu, Tapio Seppanen, Xin Liu","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2025-02-11T13:05:42Z","title":"CodePhys: Robust Video-based Remote Physiological Measurement through Latent Codebook Querying"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.07526","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:f034377347afbdf3821abba4da9c6c74cf7881cd7dd98074b5e00febc5564d38","target":"record","created_at":"2026-07-05T10:12:38Z","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":"bc23639245a97b35d632cb15284e734ee4f7204359901a47cf8d4fbdcbabe086","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2025-02-11T13:05:42Z","title_canon_sha256":"5375edf17106b3cc16a289f80dc616e96e448bcbea2164fbc13c426321bb4e43"},"schema_version":"1.0","source":{"id":"2502.07526","kind":"arxiv","version":1}},"canonical_sha256":"7233589c80b75dae47be052292f93d5f353169d6e2149e3deea9d1342b13789a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7233589c80b75dae47be052292f93d5f353169d6e2149e3deea9d1342b13789a","first_computed_at":"2026-07-05T10:12:38.833927Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:12:38.833927Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ezR3jXsa4+rg4U9+jH/TeZyrXEdhXhY4uyVF53K1CogRkBSLl9Zlys5GPZ5L721Y8We0jJl/845AOj2jWXrYDA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:12:38.834504Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.07526","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f034377347afbdf3821abba4da9c6c74cf7881cd7dd98074b5e00febc5564d38","sha256:14b2d2a620614ba117401b4baeedbc708ab3a77ea56653d636182cb9d8aef4fd"],"state_sha256":"99369127ccd4a59e2573d4b1467f9c0dc1861eb5f1960a0fb7ac93ae01985282"}
