These models often struggle with thin structures and fine boundaries, leading to poor segmentation quality. We propose Talk2SAM, a novel approach that integrates textual guidance to improve segmentation of such challenging objects. The method uses CLIP-based embeddings derived from user-provided text prompts to identify relevant semantic regions, which are then proje","authors_text":"Dmitry Yudin, Luka Vetoshkin","cross_cats":["eess.IV"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2025-06-03T19:53:10Z","title":"Talk2SAM: Text-Guided Semantic Enhancement for Complex-Shaped Object Segmentation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.05396","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":"sha256:15a83ccf58eec50ef9717d3d910f292a0d8ee7ecf91acd351150f1ba50f3910d","target":"record","created_at":"2026-07-05T11:17:01Z","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":"d0131a6d77ce6ed005a67693039fc0a356c0c580ca524665a29cef5bd94861e9","cross_cats_sorted":["eess.IV"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2025-06-03T19:53:10Z","title_canon_sha256":"ca94ec612d954f2cee363acda5c9ae5cd42f35bbd16f826176b49c8a963039cb"},"schema_version":"1.0","source":{"id":"2506.05396","kind":"arxiv","version":1}},"canonical_sha256":"66b219e51441512c461b8d7d102e0c0fa935a83a5af65ef41d1070ed64597963","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"66b219e51441512c461b8d7d102e0c0fa935a83a5af65ef41d1070ed64597963","first_computed_at":"2026-07-05T11:17:01.927212Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:17:01.927212Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"3jv8+EP4KdOf26Qd0jFD75HLZYXoAEU30hwJDrAQ6dtSlG+m/xw54MPNWuU/AxWgwdnkfz/+3nKohwB7kwwbCg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:17:01.927678Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.05396","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:15a83ccf58eec50ef9717d3d910f292a0d8ee7ecf91acd351150f1ba50f3910d","sha256:423f87108289ad5acd87cbcc90be5064884ab6739965fd9855e0d8ff2eb417cc"],"state_sha256":"b09a34c25ca1c02f4807b13b01314469f026e104ae1a54471a94fc03db3eeeb6"}
