To find the local PSF map in a computationally tractable way, we train a convolutional neural network to perform regression of an optical parametric model on synthetically blurred image patches. We deconvolved both synthetic and experimentally-acquired data, and achieved an improvement of image SNR of 1.00 dB on average, compared to other deconvo","authors_text":"Adrian Shajkofci, Michael Liebling","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-03-20T14:29:12Z","title":"Semi-Blind Spatially-Variant Deconvolution in Optical Microscopy with Local Point Spread Function Estimation By Use Of Convolutional Neural Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.07452","kind":"arxiv","version":4},"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:d4080cd4fb889ecf663b6c61771147fa1d274ee390df35414fd1188ab267e2db","target":"record","created_at":"2026-05-17T23:45:53Z","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":"20c25aa85f0ff2f4dbf532741a32641a9ad97e1a9ff937d2a876ce947e98af4d","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-03-20T14:29:12Z","title_canon_sha256":"9945806d1c084ec16c02164ab07ed1c9cd0706f3d11375a3ddf2459c0f047e26"},"schema_version":"1.0","source":{"id":"1803.07452","kind":"arxiv","version":4}},"canonical_sha256":"a42398c1506fbdd0dc6cb5f7dc48f62b5f0cfc6a05ea09de5be906e2628292bb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a42398c1506fbdd0dc6cb5f7dc48f62b5f0cfc6a05ea09de5be906e2628292bb","first_computed_at":"2026-05-17T23:45:53.191868Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:53.191868Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"iO5Dj6hAU+PuZ0Wxeg8m6DzWy25/8k++Ki7V1LDhwmy4tLvacwwAF2lFpQTn5Hhv8e7MGraVEkO+QCbV14rGBg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:53.192482Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.07452","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d4080cd4fb889ecf663b6c61771147fa1d274ee390df35414fd1188ab267e2db","sha256:62ea0444693c9a1abef1ff9df876e63e2de95d7546054d53489f41da361a2f6d"],"state_sha256":"252acc77bae703fea0ffc05d558a0e0f4b0803775584a522982240f1b51113ac"}
