More specifically, tasks like tying a knot, wiring a connector or even surgical suturing deal with the domain of Deformable Linear Objects (DLOs). In particular the detection of a DLO is a non-trivial problem especially under clutter and occlusions (as well as self-occlusions). The pose estimation of a DLO results into the identification of its parameters related to a designed model, e.g. a basis spline. It follows that the stand-alone segmentation of a DLO might not be suffic","authors_text":"Daniele De Gregorio, Gianluca Palli, Luigi Di Stefano","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-10-10T11:31:14Z","title":"Let's take a Walk on Superpixels Graphs: Deformable Linear Objects Segmentation and Model Estimation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.04461","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":"sha256:455ffea557b335a069e849d243e6ee093b08599181225ad38cd23e78daf449fd","target":"record","created_at":"2026-05-18T00:03:40Z","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":"6649a551331e3e38a7831e9c96cd1651e3c486007550650a089cf40eeb94d264","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-10-10T11:31:14Z","title_canon_sha256":"bc9fe99f10c53a1d9c1b826cea35480f32ad234ad7b47e3d1a2f461381017cb4"},"schema_version":"1.0","source":{"id":"1810.04461","kind":"arxiv","version":1}},"canonical_sha256":"e7aab6956ad8dd3748cb224609efe1ac2c87cefb079312a29b18150baf84276d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e7aab6956ad8dd3748cb224609efe1ac2c87cefb079312a29b18150baf84276d","first_computed_at":"2026-05-18T00:03:40.063221Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:03:40.063221Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+/0JjZAXP9XJDjUXFMIAM4mibQydq1DRCBjlGJQSaEG/PwhMA8xZvze3a6HIV6PEfcSRCCargh/PO8D2eKjTCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:03:40.063729Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.04461","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:455ffea557b335a069e849d243e6ee093b08599181225ad38cd23e78daf449fd","sha256:b86107965165f43f4cda578069f389ed42dd2c6f5c7cf91e52a5f712ab1a9dd5"],"state_sha256":"51cb366b3b2a4a144e59623d21627ae30e7ea7dcee89984af2ecb848f06a70d6"}
