Given a set of putative sparse matches and the camera intrinsics, we train our network in an end-to-end fashion to label the correspondences as inliers or outliers, while simultaneously using them to recover the relative pose, as encoded by the essential matrix. Our architecture is based on a multi-layer perceptron operating on pixel coordinates rather than directly on the image, and is thus simple and small. We introduce a novel normalization technique, called Context Normalization, which allows us ","authors_text":"Eduard Trulls, Kwang Moo Yi, Mathieu Salzmann, Pascal Fua, Vincent Lepetit, Yuki Ono","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-11-16T07:54:57Z","title":"Learning to Find Good Correspondences"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.05971","kind":"arxiv","version":2},"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:c74210199667804d6c885c80a1e3b49c8b41d318c0638a7a028f434b625d254e","target":"record","created_at":"2026-05-18T00:15:37Z","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":"f7e9126c4d2cd15ecd37960ae81f1451e25470a7a17812c5fb0b03b9ed25935b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-11-16T07:54:57Z","title_canon_sha256":"61b58daa62cdcbbf0ead3ec888063799c87fb62d34017f29750b926538fba634"},"schema_version":"1.0","source":{"id":"1711.05971","kind":"arxiv","version":2}},"canonical_sha256":"8a3d5f788596ba47d97c15735bc07cc4cbe57cacf376d1465fff3f0fdb0365c7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8a3d5f788596ba47d97c15735bc07cc4cbe57cacf376d1465fff3f0fdb0365c7","first_computed_at":"2026-05-18T00:15:37.016435Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:15:37.016435Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JdJ/K8/JznM5an871wEz3Z99+y77ucwzXGqZ7mE3ojceUNeoYGSpDSCtocvwyYllyhVy8HmEMFGC8EsObHvLCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:15:37.016865Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.05971","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c74210199667804d6c885c80a1e3b49c8b41d318c0638a7a028f434b625d254e","sha256:316313fb4626d55b259b4b0c12f608af021ee2283fe53df853700dd8b7cdf02c"],"state_sha256":"c13b0a2b2017aa485383d3a11b128eb6eb029057fd56e819006d3c66fa919f5a"}
