Among all motion estimation approaches, Block-matching (BM) algorithms are the most popular methods due to their effectiveness and simplicity for both software and hardware implementations. A BM approach assumes that the movement of pixels within a defined region of the current frame can be modeled as a translation of pixels contained in the previous frame. In this procedure, the motion vector is obtained by minimizing a certain matching metric that is produced for the current frame over a determined search","authors_text":"Erik Cuevas","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2014-06-17T19:13:40Z","title":"Block matching algorithm based on Harmony Search optimization for motion estimation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.4484","kind":"arxiv","version":1},"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:e0037907d9fc98f008e2c7afe7ac7cc551c020a3c64b3d149684d0ac113904b7","target":"record","created_at":"2026-05-18T02:49:31Z","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":"a8327b7566467879cba0483db2fefbbe4d8a478c261ab606878a1c3dae9b44bc","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2014-06-17T19:13:40Z","title_canon_sha256":"b7f05555b319f9a106bc8abff0cfd6eb6738ff055f4a2d6e7b92685052a71d1a"},"schema_version":"1.0","source":{"id":"1406.4484","kind":"arxiv","version":1}},"canonical_sha256":"1268e08353a737bbc1a93289622f6e7d4ac29defc2b151b70d37e1dfc3411d79","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1268e08353a737bbc1a93289622f6e7d4ac29defc2b151b70d37e1dfc3411d79","first_computed_at":"2026-05-18T02:49:31.963781Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:49:31.963781Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9GqfgEjfjTrn8f2+MB1VBe38JkmN5pnR3QhGHaSpYqR2wgq6MYfVFV5xM18A1aHag0a9bNaSdejjDZElDNHKAw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:49:31.964386Z","signed_message":"canonical_sha256_bytes"},"source_id":"1406.4484","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e0037907d9fc98f008e2c7afe7ac7cc551c020a3c64b3d149684d0ac113904b7","sha256:7207d93123bb121b03e75f5fd855d85ed3063c3ac859fa55ab9712e327bbefe3"],"state_sha256":"2d6ebefeba3f3ae0b684c821a6d9080f1a8db89ab43a0e4d231676d259f6d092"}
