However, even nowadays it is still a challenging task to devise a method that combines the flexibility to work on non-trivial computational domains with high accuracy, robustness and computational efficiency. By uniting a classic approach for surface normal integration with modern computational techniques we construct a solver that fulfils these requirements. Building upon the Poisson integration model we propose to use an iterative Krylov subspace solver ","authors_text":"Ali Sharifi Boroujerdi, Jean-Denis Durou, Martin B\\\"ahr, Michael Breu{\\ss}, Yvain Qu\\'eau","cross_cats":["cs.CV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NA","submitted_at":"2016-10-19T15:01:09Z","title":"Fast and Accurate Surface Normal Integration on Non-Rectangular Domains"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1610.06049","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":"sha256:7462b5128e9c9646e22205dde9ba8c5ee70d78ea6b01241c3e00e7076c511a3b","target":"record","created_at":"2026-05-18T01:01:50Z","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":"558e137db7133fa98e90ef35c8d972f5afe7287dc2968dee80c940815605621d","cross_cats_sorted":["cs.CV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NA","submitted_at":"2016-10-19T15:01:09Z","title_canon_sha256":"d40b932f10d1cb19eedbbc9ac02faaceab3ba2d5873db47fe487b34a3a2382bf"},"schema_version":"1.0","source":{"id":"1610.06049","kind":"arxiv","version":1}},"canonical_sha256":"89cc1637bf20965066f35d297a2be1370ac4436cfcb031ddd6d463e83ab47d2e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"89cc1637bf20965066f35d297a2be1370ac4436cfcb031ddd6d463e83ab47d2e","first_computed_at":"2026-05-18T01:01:50.282532Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:01:50.282532Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ncXs6dnUAQKhCBbhpzzlZTqIWrjn2KABNCVDENr8q+WXIRJKkLMrl4ZzWV7AXETFvV9i02M3GwSZanXoJZnkAg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:01:50.283191Z","signed_message":"canonical_sha256_bytes"},"source_id":"1610.06049","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7462b5128e9c9646e22205dde9ba8c5ee70d78ea6b01241c3e00e7076c511a3b","sha256:03c1fcdf91d326a1364e5256501b7838f0e5995123b6aecb7b691108eabfb2ab"],"state_sha256":"523dd5f1811d8eb78f9765287a50def5130e50e96fd24cffded3fb6b0c630d7b"}
