Current min-cost flow algorithms which solve the data association problem optimally have three main drawbacks: they are computationally expensive, they assume that the whole video is given as a batch, and they scale badly in memory and computation with the length of the video sequence. In this paper, we address each of these issues, resulting in a computationally and memory-bounded solution. First, we introduce a dynamic version of the successive shortest-path algorithm which solves the data association probl","authors_text":"Andreas Geiger, Philip Lenz, Raquel Urtasun","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2014-07-23T15:07:12Z","title":"FollowMe: Efficient Online Min-Cost Flow Tracking with Bounded Memory and Computation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1407.6251","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":"sha256:5f908c39eda5fb244c46003d291acd3866c68a5a896f25062dfb8dfeb0165f72","target":"record","created_at":"2026-05-18T02:30:31Z","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":"fbe0253e1ba82cd61934e8ae055e67907637fa93567579db85f15aa44c6e5aba","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2014-07-23T15:07:12Z","title_canon_sha256":"2f29ec342b106a93f646fd69e3dd0d90f26ed35e71fd75ee99785d0f3cc37d95"},"schema_version":"1.0","source":{"id":"1407.6251","kind":"arxiv","version":2}},"canonical_sha256":"ef25e0ab427273fbdb4db3aa8ee238b324336478d5091d8f43dea31b35ef23fc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ef25e0ab427273fbdb4db3aa8ee238b324336478d5091d8f43dea31b35ef23fc","first_computed_at":"2026-05-18T02:30:31.805721Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:30:31.805721Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"933GNicTfP5DG4W413R7oHj2HBsN0FGrP8Hn7SIvGsdg17TjJYSVNBpIApIIx/97Se33qEyunUk63Qjykv0bCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:30:31.806285Z","signed_message":"canonical_sha256_bytes"},"source_id":"1407.6251","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5f908c39eda5fb244c46003d291acd3866c68a5a896f25062dfb8dfeb0165f72","sha256:8815cbc66bf0c40f502bb0762a5626f8148682b30d26979fb4b9cb04c0a65b4b"],"state_sha256":"5fbde18cec2bcf2ab943cc5a6b1a21f7be7e63529df154abda2f2a715b9d04e3"}
