In this paper, we present novel meta-descriptors based on a hierarchical distribution of pixel features. Although hierarchical covariance descriptors have been successfully applied to image classification, the mean information of pixel features, which is absent from the covariance, tends to be the major discriminative information for person re-id. To solve this problem, we describe a local region in an image via hierarchical Gaussian distribution in which both","authors_text":"Einoshin Suzuki, Takahiro Okabe, Tetsu Matsukawa, Yoichi Sato","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-06-14T05:16:16Z","title":"Hierarchical Gaussian Descriptors with Application to Person Re-Identification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.04318","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":"sha256:72e66f957b608ef52e0520b3830b3b6fcae67ce002ccdb7cb19f17518fbcd28a","target":"record","created_at":"2026-05-18T00:42:22Z","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":"0a4f019c6642951ec1652087b455e1019d88b440e4fac6affe930c8463a43d4d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-06-14T05:16:16Z","title_canon_sha256":"b086260727c3048220cd8e8915e604b6a7bab465a5aec70097fe8b8c59639c82"},"schema_version":"1.0","source":{"id":"1706.04318","kind":"arxiv","version":1}},"canonical_sha256":"d12cab46d65b0c0f8272d425e83942ed991f108271b8ecde070f0da1a6f1366c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d12cab46d65b0c0f8272d425e83942ed991f108271b8ecde070f0da1a6f1366c","first_computed_at":"2026-05-18T00:42:22.999615Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:42:22.999615Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kmKN6XroqlEhutMjADHn6zwI1M5Xp4Y5f9mFO3fncYio6FgDhyNz50FwPsAzlkCyTxBH63odCfTwgE5doE66DA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:42:23.000078Z","signed_message":"canonical_sha256_bytes"},"source_id":"1706.04318","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:72e66f957b608ef52e0520b3830b3b6fcae67ce002ccdb7cb19f17518fbcd28a","sha256:2a533879094b2071a4492d67333f43ee4769db8fb2e85e34da6fb491c623d440"],"state_sha256":"44260b8639638789d4a47a219917bcab9c56c3b5727d7165057e4a2bb26c8fd2"}
