Extending RIS to endoscopic imagery, however, presents unique challenges, including scarce high-quality annotations and complex, domain-specific image-text relationships. Although recent vision-language models demonstrate strong cross-domain alignment, they often fail to capture fine-grained textual cues in endoscopic settings, resulting in suboptimal performance and limited generalization. To address these challenges, we introduce ReferEn","authors_text":"David Doermann, Nan Xi, Shun Liu, Tianyu Luan, Xuan Gong, Yang Liu","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-07-09T12:21:06Z","title":"Attribute Retrieving for Open-Vocabulary Endoscopic Compositional Referring Segmentation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.08397","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":"sha256:319b1eb9cee31a51bf66cf75ffa4df5e53c611105cca97c8b9bd395c6d7a8379","target":"record","created_at":"2026-07-10T01:19:49Z","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":"7e998ac360f2cad2d59887e6506dd6c23ab6800739e5a1f9be0f9f5d0199f8ab","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-07-09T12:21:06Z","title_canon_sha256":"1fce2105ddc4dc864475368c0a35883849c5ee55a884effd72eb52021d15f14d"},"schema_version":"1.0","source":{"id":"2607.08397","kind":"arxiv","version":1}},"canonical_sha256":"e69d947d957da6258f8b56522931e4c0025eef3b88f69c9282c667715ed94e64","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e69d947d957da6258f8b56522931e4c0025eef3b88f69c9282c667715ed94e64","first_computed_at":"2026-07-10T01:19:49.058286Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-10T01:19:49.058286Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+cnPjvf5gLrTD0rfFKF3bE//dwSs5Q5BK26Lez3aAdBa6eIIxlW0PAagrtj1ac0majzuDtDa22sNQ3r0JN+8BQ==","signature_status":"signed_v1","signed_at":"2026-07-10T01:19:49.058688Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.08397","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:319b1eb9cee31a51bf66cf75ffa4df5e53c611105cca97c8b9bd395c6d7a8379","sha256:9c1f2ff5fb1a8d28c011b069afbd43dec81c4b8831bf7aab8e9745d1324fd0a6"],"state_sha256":"9d9dab8d3fb259cf08f384077473d8e6bea637090bf9fbb33680dec846f80400"}
