R2-IOS consists of a reversible proposal refinement sub-network that predicts bounding box offsets for refining the object proposal locations, and an instance-level segmentation sub-network that generates the foreground mask of the dominant object instance in each proposal. By being recursive, R2-IOS iteratively optimizes the two sub-networks during joint training, in which the refined object proposals and improved segme","authors_text":"Jiashi Feng, Liang Lin, Shuicheng Yan, Xiaodan Liang, Xiaohui Shen, Yunchao Wei, Zequn Jie","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2015-11-14T06:10:41Z","title":"Reversible Recursive Instance-level Object Segmentation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.04517","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:e0c836146947e965568cb95bd3c161d5107cf76674cc169656b03798d9ce9647","target":"record","created_at":"2026-05-18T01:26:33Z","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":"ad0833e519b4f20028a2a43bef935d03309220af9a81913ca18055440f725b2f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2015-11-14T06:10:41Z","title_canon_sha256":"9afd334257ece549e54994fc3148be8eb2fad854a37efc3c5005b14809e4502d"},"schema_version":"1.0","source":{"id":"1511.04517","kind":"arxiv","version":2}},"canonical_sha256":"2bb4e915f8e1b39da882458e91ba4e3fe2598df300c5d76e016ba848b59e7864","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2bb4e915f8e1b39da882458e91ba4e3fe2598df300c5d76e016ba848b59e7864","first_computed_at":"2026-05-18T01:26:33.445789Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:26:33.445789Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XvgNBStVwO+xXQ9FUOYcL1RlaU8+ZD0Ia9tMNkML/L7MqChm7oaxeoZTDKmsZKdUaK4pZDow0AreqMF1CeSzBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:26:33.446423Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.04517","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e0c836146947e965568cb95bd3c161d5107cf76674cc169656b03798d9ce9647","sha256:2cff6a3b4b8a93a8958c4e5d3d0b69158d6277839ffea58e03f1fed0051c6ea6"],"state_sha256":"2bd98f6604415fb778d7b8f9d00a892d470d65eb39f0013d3b5ceef01ea16eda"}
