Our methodology is divided into two stages. Initially, we extract 3D intermediate representations from audio and project them into a sequence of 2D facial landmarks. Subsequently, we employ a robust diffusion model, coupled with a motion module, to convert the landmark sequence into photorealistic and temporally consistent portrait animation. Experimental results demonstrate the superiority of AniPortrait in terms of facial naturalness, pose diversity, ","authors_text":"Huawei Wei, Zejun Yang, Zhisheng Wang","cross_cats":["cs.GR","eess.IV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2024-03-26T13:35:02Z","title":"AniPortrait: Audio-Driven Synthesis of Photorealistic Portrait Animation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2403.17694","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:a50354812afa1e119e9b18bc5e5157542c8020862d79888fb183e25d3017fa96","target":"record","created_at":"2026-07-05T08:00:54Z","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":"a05129358a4304020da69b0364176700f7e6ab2b9dd95f7a487466c9541cd211","cross_cats_sorted":["cs.GR","eess.IV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2024-03-26T13:35:02Z","title_canon_sha256":"33384b009ea17500acd19b2e10094f17bcbf3934abdcc5ef48f64d673bc12dc1"},"schema_version":"1.0","source":{"id":"2403.17694","kind":"arxiv","version":1}},"canonical_sha256":"e1da61dbf67068250e7aa3a54c5f52d3696b1f8cfe0392f58a9176cb775cc141","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e1da61dbf67068250e7aa3a54c5f52d3696b1f8cfe0392f58a9176cb775cc141","first_computed_at":"2026-07-05T08:00:54.453742Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:00:54.453742Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"E9sOQZrnlALx3weFP0r/kx7maRUC1eudTYDtCaGZ7bgf5b8Ow/pHxopmi9jifDcehVCIeyIinjqw8wKDl6mhBw==","signature_status":"signed_v1","signed_at":"2026-07-05T08:00:54.454181Z","signed_message":"canonical_sha256_bytes"},"source_id":"2403.17694","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a50354812afa1e119e9b18bc5e5157542c8020862d79888fb183e25d3017fa96","sha256:d5be6f385d7efe20b8b8121537f75eaa9121c20d9de7130f8642669f6470f7af"],"state_sha256":"9fac46b005d40cdc32d2d964eda6566ba825296decc3b98eeb5acacc5b7d0f72"}
