However, existing MPF solutions are not completely satisfactory. Firstly, they often fail to track the target at a close distance either because they are based on a visual servo or they need the observation of the full body by the robot. Secondly, their target Re-IDentification (Re-ID) abilities are weak in cases of target appearance change and highly similar appearance of distracting people. To remove the assumption of full-body observation, we propose a width-based tracking module, whic","authors_text":"Hanjing Ye, Hong Zhang, Jieting Zhao, Weinan Chen, Yaling Pan","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2022-04-22T07:13:05Z","title":"Following Closely: A Robust Monocular Person Following System for Mobile Robot"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2204.10540","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":"sha256:8f19cb6e9cef7512f7831f54d21c891d6b279a6f1d50655b1878b84ec87783e9","target":"record","created_at":"2026-07-05T04:17:22Z","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":"2e4af08c1785675073b03a79e0f536bd4b066323abba7a657219e412b7352c4e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2022-04-22T07:13:05Z","title_canon_sha256":"1864b5f53b7ec309bf5442c81324b1c1c42f409ea130da53b0ba5d4e5a1f0d96"},"schema_version":"1.0","source":{"id":"2204.10540","kind":"arxiv","version":2}},"canonical_sha256":"9d4765aa12c38de73d9f68fe548d6baf99163a0b0a27b6eca161dfab370e63ba","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9d4765aa12c38de73d9f68fe548d6baf99163a0b0a27b6eca161dfab370e63ba","first_computed_at":"2026-07-05T04:17:22.985010Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:17:22.985010Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"sUI2TWJ9UeJyFgg/syArVRD71ppNZCSJiaQy0wu9wbSa7GCGd2DbdNVKQEf4iAodq5UiP7NfQGqhe4ZM0a02Aw==","signature_status":"signed_v1","signed_at":"2026-07-05T04:17:22.985505Z","signed_message":"canonical_sha256_bytes"},"source_id":"2204.10540","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8f19cb6e9cef7512f7831f54d21c891d6b279a6f1d50655b1878b84ec87783e9","sha256:1c93f7738e3157acfea29f8e5fd041e3c1de280fcb7612e209b6f6bd6f200dd6"],"state_sha256":"86ade6b476cbcaa97c4f1e8f598b390a5220e04839d505d11eb81dcbc8984239"}
