While this area of research has gained much attention recently, most works still rely on hand-crafted features. In contrast, we apply a multiscale convolutional network to learn features directly from the images and the depth information. We obtain state-of-the-art on the NYU-v2 depth dataset with an accuracy of 64.5%. We illustrate the labeling of indoor scenes in videos sequences that could be processed in real-time using appropriate hardware such as an FPGA.","authors_text":"Camille Couprie, Cl\\'ement Farabet, Laurent Najman, Yann LeCun","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2013-01-16T03:31:30Z","title":"Indoor Semantic Segmentation using depth information"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1301.3572","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":"sha256:1296302fbd3d6b5b9c0c053723aff4ef4823d087c064f0560c014fb8bc5ee6e5","target":"record","created_at":"2026-05-18T03:30:55Z","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":"b13595b1b02f1876ff2ef18bdc921cb0a086027944b8337ee8403dd8bfc143ef","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2013-01-16T03:31:30Z","title_canon_sha256":"09747cdcefeeada991389838f05ea4c51abe41e95481f2603917d16fe5ccff70"},"schema_version":"1.0","source":{"id":"1301.3572","kind":"arxiv","version":2}},"canonical_sha256":"787862e2459b7122475756b0c33e8acbbe920ea4191bf0eb6cbdea6c16ab67f2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"787862e2459b7122475756b0c33e8acbbe920ea4191bf0eb6cbdea6c16ab67f2","first_computed_at":"2026-05-18T03:30:55.023431Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:30:55.023431Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vRpmzoGdu6jkuidtJYVVy2j/df8DaguV9GLb+l9zz70YqShdfDVDwjmO5nkJY6ljsT+pN9ivDX2L710fsqO+AQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:30:55.024122Z","signed_message":"canonical_sha256_bytes"},"source_id":"1301.3572","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1296302fbd3d6b5b9c0c053723aff4ef4823d087c064f0560c014fb8bc5ee6e5","sha256:cb21326593bc2febf14499eb6f28f31e0515e2e0aab7b476c77fb8a67cd36c16"],"state_sha256":"7dffe2267767168e90e282a99b9a671f1869d30ae2c16c68ec0941a2e2d66190"}
