However, these methods rely exclusively on the referred target for supervision, overlooking the potential benefits of prominent prospective targets. Moreover, existing approaches often fail to incorporate multi-granularity discrimination, which is crucial for robust object identification in complex scenarios. To address these limitations, we propose PropVG, an end-to-end pr","authors_text":"Hongshen Zhao, Jiang-Jiang Liu, Jiedong Zhuang, Ming Dai, Wankou Yang, Wenxuan Cheng, Zhenhua Feng","cross_cats":["cs.AI"],"headline":"","license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2025-09-05T06:30:06Z","title":"PropVG: End-to-End Proposal-Driven Visual Grounding with Multi-Granularity Discrimination"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2509.04833","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":"sha256:967067735535fa3025c311a63f3801adfdc97fa1804a7a646a8eaaaa4dbc1888","target":"record","created_at":"2026-07-05T12:05:30Z","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":"932f60fcba78bc8ef865cc454b7aede6237492f87bb456f0edf9b7538eada569","cross_cats_sorted":["cs.AI"],"license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2025-09-05T06:30:06Z","title_canon_sha256":"4015115e8f84a0c17db68d29a3ebcbd1e90c22ec74f97572308032e96e19ba3d"},"schema_version":"1.0","source":{"id":"2509.04833","kind":"arxiv","version":1}},"canonical_sha256":"98bf0839776943f82f82aae7f4013b44ff93d78887766bcbd4c12004dae06013","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"98bf0839776943f82f82aae7f4013b44ff93d78887766bcbd4c12004dae06013","first_computed_at":"2026-07-05T12:05:30.530150Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T12:05:30.530150Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TaY1L85VjHoy53qzp7CzcZs1QDNeOMxjYEC8rIzDTg4aVTuEXGMO8qUwOHHa/k3iCYxwOspfzv4HYajKkfleBg==","signature_status":"signed_v1","signed_at":"2026-07-05T12:05:30.530720Z","signed_message":"canonical_sha256_bytes"},"source_id":"2509.04833","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:967067735535fa3025c311a63f3801adfdc97fa1804a7a646a8eaaaa4dbc1888","sha256:c2174153a494a3c63fd4e73d335fbe115fa4befa68c55461407c6988370b5589"],"state_sha256":"b737063e1362792f11fc69eeb2654559b3932f413f3a7afe8734069ee6a7eddc"}
