This paper presents a novel principled Partially Observable Markov Decision Process-based approach to coordinating and controlling a network of active cameras for tracking and observing multiple mobile targets at high resolution in such surveillance environments. Our proposed approach is capable of (a) maintaining a belief over the targets' states (i.e., locations, directions, and velocities) to track them, even when they may not be observed directly by the cam","authors_text":"Kian Hsiang Low, Mohan Kankanhalli, Prabhu Natarajan, Trong Nghia Hoang","cross_cats":["cs.MA","cs.MM","cs.RO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2012-09-19T15:15:08Z","title":"Decision-Theoretic Coordination and Control for Active Multi-Camera Surveillance in Uncertain, Partially Observable Environments"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1209.4275","kind":"arxiv","version":3},"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:c61587d225af90e63d60c683b1cdf02a6665a87addbc8d64f19006041738b0b3","target":"record","created_at":"2026-05-18T03:44:15Z","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":"84a062026dc22ca4cbb075d7de9e8f8c7c1a44e554d0ad173c08d4ba9cb6486e","cross_cats_sorted":["cs.MA","cs.MM","cs.RO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2012-09-19T15:15:08Z","title_canon_sha256":"bf5e8ddccf49325c43213bb456d77387250542334b678ccb2105a3dd2be9db68"},"schema_version":"1.0","source":{"id":"1209.4275","kind":"arxiv","version":3}},"canonical_sha256":"570b2407632df311769d347bb7663f03c046e5de5ca4d610148593adf892b55d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"570b2407632df311769d347bb7663f03c046e5de5ca4d610148593adf892b55d","first_computed_at":"2026-05-18T03:44:15.019619Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:44:15.019619Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"u4eShySa6e9CvN3Tpt4PR5SWX3zC4+E7jLdHylPD70U/Yz/JjrVpBEjRydJyE3RUCDkWf5qvsSs5H0JvNxylAA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:44:15.020081Z","signed_message":"canonical_sha256_bytes"},"source_id":"1209.4275","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c61587d225af90e63d60c683b1cdf02a6665a87addbc8d64f19006041738b0b3","sha256:8bc1b34128486ebe31fef2479a473ae166a34b05b40ea788c10f0c1aae2265d2"],"state_sha256":"9ef6da67b669ea7f79bb40b6d81e1e762673244e677714cad056e24950070ed6"}
