This paper presents a study on removing identity information while preserving FER capabilities. Drawing on the observation that low-frequency components predominantly contain identity information and high-frequency components capture expression, we propose a novel two-stream framework that applies privacy enhancement to each component separately. We introduce a controlled privacy enhancement mechanism to optimize performance and a feature compensator t","authors_text":"Dadong Wang, David Ahmedt-Aristizabal, Feng Xu, Lars Petersson, Xun Li","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2024-11-29T23:12:38Z","title":"Facial Expression Recognition with Controlled Privacy Preservation and Feature Compensation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.00277","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":"sha256:5f126537325aef2cd465a087497ff32778dcca5b666eec76cfebca28d9a6dd76","target":"record","created_at":"2026-07-05T09:43:38Z","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":"397d19114fb14a0159ed066a280d6f8ce8030289a3a1f84ab5d7c9abd13c49a0","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2024-11-29T23:12:38Z","title_canon_sha256":"ce624b4f1bbe5b92252fcd2e8a05a51524e0c54b8b24bff8fe8874ad21bae370"},"schema_version":"1.0","source":{"id":"2412.00277","kind":"arxiv","version":2}},"canonical_sha256":"a0c9b819791d7d0745bc295d2e6b482aad2af59e586cbc3fcbf39ddeafee3bf6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a0c9b819791d7d0745bc295d2e6b482aad2af59e586cbc3fcbf39ddeafee3bf6","first_computed_at":"2026-07-05T09:43:38.098479Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:43:38.098479Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hU6pF0nTTPwRTk1IMZ+DxEWpFIP50m2X8tNWlWe0e/RsnDEzynYpknSKFSZJu4ICNWVvre/X7Z9yZLPr0x4NBA==","signature_status":"signed_v1","signed_at":"2026-07-05T09:43:38.099045Z","signed_message":"canonical_sha256_bytes"},"source_id":"2412.00277","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5f126537325aef2cd465a087497ff32778dcca5b666eec76cfebca28d9a6dd76","sha256:260e0b3cbedbb5a9974eebc3f96cb50b3e2da3503050489a52350976a4749bb6"],"state_sha256":"172435fe255cc3e0927689ea3d65d08a6353892ef65e7a589e93cc697d849765"}
