This information can be further applied to a appropriate system to automatically correct this position. The algorithm is based on the evaluation of a so called resolution function who calculates the maximum of gradient in a certain zone of the image. The paper also presents alternative forms of the function, results of measurements and set up a set of practical rules for the right application of the algorithm.","authors_text":"Radu Arsinte","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2015-02-21T07:40:18Z","title":"Study of a Robust Algorithm Applied in the Optimal Position Tuning for the Camera Lens in Automated Visual Inspection Systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1502.06081","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":"sha256:2ad33233bd3bf76ca61de78d9347725cc3e718b109877f88ae17fb015d8a3a4c","target":"record","created_at":"2026-05-18T02:26:38Z","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":"c0a03b3ee7d993aa293bcf2b0a33d434a00924fe383701e8797d58b40b71c8ea","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2015-02-21T07:40:18Z","title_canon_sha256":"052152e5ddd4e20d9b5f7fca33b6919ddeddc1f1c26ea5e8787e05f3d6fd4c61"},"schema_version":"1.0","source":{"id":"1502.06081","kind":"arxiv","version":1}},"canonical_sha256":"72d6c77588b59c6460132027268afb721b22a2919d2907448cfc28ccbe25266b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"72d6c77588b59c6460132027268afb721b22a2919d2907448cfc28ccbe25266b","first_computed_at":"2026-05-18T02:26:38.114078Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:26:38.114078Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"i/50Tetf4u8e8FU1SyzRcU9PuoBeYhjMh0Z7mT65Qr3GRg+IdnfX1opWvOnZXWjcBFIT1QhL5DU/zoqSkw7qCg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:26:38.114568Z","signed_message":"canonical_sha256_bytes"},"source_id":"1502.06081","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2ad33233bd3bf76ca61de78d9347725cc3e718b109877f88ae17fb015d8a3a4c","sha256:3cdca9abb1d869bcf7dc406321617afb3b7ca0eb32fcbfad55159c6d76ef988e"],"state_sha256":"1d74d9296014ec9c941fce49c0f91c991a78005164c20c0156661574d8023a16"}
