Despite notable advancements, the reconstruction of complex and dynamic head movements from monocular videos still suffers from capturing and restoring fine-grained details. In this work, we propose a novel approach, named Tri$^2$-plane, for monocular photo-realistic volumetric head avatar reconstructions. Distinct from the existing works that rely on a single tri-plane deformation field for dynamic facial modeling, the proposed Tri$^2$-plane leverages the principle of feature py","authors_text":"Chenliang Xu, Guojun Yin, Lele Chen, Luchuan Song, Pinxin Liu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2024-01-17T17:59:03Z","title":"Tri$^{2}$-plane: Thinking Head Avatar via Feature Pyramid"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2401.09386","kind":"arxiv","version":3},"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:c96d71e3019533502db3c12c8efdbc543e44caab1adcc27ae041e55a1510d4be","target":"record","created_at":"2026-07-05T08:42:32Z","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":"3232620dcdf9cd7a1f3a72412a44123d1f05574c933acd8a582d747342d06b3e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2024-01-17T17:59:03Z","title_canon_sha256":"80f99cbf7bd689b411192e9df3845b77465c585f7c7e246a15e41344b747c71f"},"schema_version":"1.0","source":{"id":"2401.09386","kind":"arxiv","version":3}},"canonical_sha256":"84e5ae4945858ba296b0d4ce9081a22c3964132602caa9363056b853d033c6ba","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"84e5ae4945858ba296b0d4ce9081a22c3964132602caa9363056b853d033c6ba","first_computed_at":"2026-07-05T08:42:32.280122Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:42:32.280122Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UwYtYlN4v5n/LlPEOqC4DCsg1wwcOXvvIn4n/wnyY/2s44LpMwVA6xRrcmxPrL+Le62WCJKQHCrT5iOFmvKMBg==","signature_status":"signed_v1","signed_at":"2026-07-05T08:42:32.280611Z","signed_message":"canonical_sha256_bytes"},"source_id":"2401.09386","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c96d71e3019533502db3c12c8efdbc543e44caab1adcc27ae041e55a1510d4be","sha256:f90cbbd4b350b2aa6c4b8f97b5524f3e39205637f565b7669397630e39d21453"],"state_sha256":"99a2ff5db08d1763bafa469b122c890e47fa04cb5e96e3186f5126c21b3d9a82"}
