In this paper, a robotic grasp detection algorithm named ROI-GD is proposed to provide a feasible solution to this problem based on Region of Interest (ROI), which is the region proposal for objects. ROI-GD uses features from ROIs to detect grasps instead of the whole scene. It has two stages: the first stage is to provide ROIs in the input image and the second-stage is the grasp detector b","authors_text":"Hanbo Zhang, Nanning Zheng, Site Bai, Xinwen Zhou, Xuguang Lan, Zhiqiang Tian","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2018-08-30T14:31:18Z","title":"ROI-based Robotic Grasp Detection for Object Overlapping Scenes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.10313","kind":"arxiv","version":6},"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":"sha256:971c5bbd0adce7218137ff07e5f600e146e8f407edb6b2a98adaf6077dd09b0d","target":"record","created_at":"2026-05-17T23:51:19Z","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":"39ca3781933b62634973dcd25e12ab8aeb3b12bac28ae29695d675a1be1901ce","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2018-08-30T14:31:18Z","title_canon_sha256":"5313452b882a4e2e75fcc64762f6839c0bee379680dbf33d18021e4cbeb01875"},"schema_version":"1.0","source":{"id":"1808.10313","kind":"arxiv","version":6}},"canonical_sha256":"d3cd3919b6e63d292ed0f8562bd0e9b18344edceca3447d544fc74bde18e43b4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d3cd3919b6e63d292ed0f8562bd0e9b18344edceca3447d544fc74bde18e43b4","first_computed_at":"2026-05-17T23:51:19.561035Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:51:19.561035Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NRlY1g7XQFQBm3BnLNKFQrCnjjk1fyqWmuw7OBp79gOnsb1BS9xw/x6nVSFMNNuH6BKMgAI7XSyuNMJtGyzmAA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:51:19.561641Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.10313","source_kind":"arxiv","source_version":6}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:971c5bbd0adce7218137ff07e5f600e146e8f407edb6b2a98adaf6077dd09b0d","sha256:52f6523b0263d8a37a28405382483920b4da66e128c535b17772587783773cbf"],"state_sha256":"9d0f86b82ed1d3e83e5e2f49e7fe597286d222f9bbca5aa2a2eff3a2191d91ec"}
