Retinex theory addresses this by viewing an image S as the pixel-wise product of reflectance R and illumination I, mirroring the way people perceive stable object colors under changing light. The decomposition is ill-posed, and classic Retinex models have four key flaws: (i) they treat the red, green, and blue channels independently; (ii) they lack a neuroscientific model of color vision; (iii) they cannot perfectly rebuild the input image; and (iv) they do not explain","authors_text":"Sos Agaian, Vladimir Frants","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2025-07-22T15:17:24Z","title":"QRetinex-Net: Quaternion-Valued Retinex Decomposition for Low-Level Computer Vision Applications"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.16683","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:c5a7fc8b27bc5eacdf5b7a6a5e56c7cbcaef5635dddc1547aab0e1bca6bfd42c","target":"record","created_at":"2026-07-05T11:41:29Z","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":"91bc4815b27bbe03400b578fc27ca392873ee929302cce469bf03511bb79707d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2025-07-22T15:17:24Z","title_canon_sha256":"9c5ed353bb0a0d21199c2429e028ccf3b77d0fc9a95080694b1de93cb9c64f97"},"schema_version":"1.0","source":{"id":"2507.16683","kind":"arxiv","version":1}},"canonical_sha256":"1585731aee58d002ea014dd37f305b0694563c0264da77c701562fc4cfdd5406","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1585731aee58d002ea014dd37f305b0694563c0264da77c701562fc4cfdd5406","first_computed_at":"2026-07-05T11:41:29.088648Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:41:29.088648Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+ZndavrU/VlKqya5LPDW9weN8ApqYLK970vxXYmJPIz/2te8Ldgw8cHoahGCUOwp4TC4jt5p2m47Kzh1k6rACg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:41:29.089113Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.16683","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c5a7fc8b27bc5eacdf5b7a6a5e56c7cbcaef5635dddc1547aab0e1bca6bfd42c","sha256:e7df57e465adc03dcf729696af840cc5c6aed94b1214414340080c3d3aa65da5"],"state_sha256":"0940ebcc182cec1b3c0ac12e3a1615b968afeb05870602f28fa7875b559bcc68"}
