This makes the process of capturing outdoor environment maps notoriously challenging since special equipment must be used. In this work, we propose an alternative approach. We first capture lighting with a regular, LDR omnidirectional camera, and aim to recover the HDR after the fact via a novel, learning-based inverse tonemapping method. We propose a deep autoencoder framework which regresses linear, high dynamic range data from non-linear, saturated, low dynamic range panoramas. We validate our method through a wide set of experiments on syn","authors_text":"Jean-Fran\\c{c}ois Lalonde, Jinsong Zhang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-03-29T19:10:27Z","title":"Learning High Dynamic Range from Outdoor Panoramas"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.10200","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":"sha256:41c06acaff90680370bc327234cc5815416447d1ddfbe1dd77235edae6e93e47","target":"record","created_at":"2026-05-18T00:31:13Z","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":"39f14937dd939d0255606b9aa2136076802b0be7fb4b52683456dc0f1a50992b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-03-29T19:10:27Z","title_canon_sha256":"80716a935d68f52b23c55ccb6309c1bfdbf8629b54b1bc57ea14706eb3fde81c"},"schema_version":"1.0","source":{"id":"1703.10200","kind":"arxiv","version":4}},"canonical_sha256":"db53217296a960e7c158c70da4971db88078de8c15c024d447d2df31c797be65","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"db53217296a960e7c158c70da4971db88078de8c15c024d447d2df31c797be65","first_computed_at":"2026-05-18T00:31:13.174556Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:31:13.174556Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"sr7LrDb2e2Q8wbchE/fFNA7CBufpUzHx3MOpMWZKoqT26GydmcHA7GZ3AzCL+Pcq16KosiLFHu7SZ506a/ruCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:31:13.175160Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.10200","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:41c06acaff90680370bc327234cc5815416447d1ddfbe1dd77235edae6e93e47","sha256:66a7d99f5cd26e83aad1f966002e2d4ea5a9c10cc5b5b580d70491d44fa28ea2"],"state_sha256":"314e057348aae381d9aeb8591aff133255d5aed72cb4ce6c6939533df7f2844f"}
