We exploit the natural long-range dependencies enabled by the attention mechanism to allow our approach to synthesize diverse textures while preserving their structures in a single inference. We propose a hierarchical hourglass backbone that attends to the global structure and performs patch mapping at varying scales in a coarse-to-fine-to-coarse stream. Completed by skip connection and convolution designs that propagate and fuse information at different scales, our hierarchical U-Attention architecture unifies ","authors_text":"Arthur Roullier, Douglas Noll, Shouchang Guo, Valentin Deschaintre","cross_cats":["cs.GR","eess.IV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2022-02-23T18:58:56Z","title":"Paying U-Attention to Textures: Multi-Stage Hourglass Vision Transformer for Universal Texture Synthesis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2202.11703","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":"sha256:76c7b36161d81cdcc2ea5bc85e177f7781766541a1548489307a0f7501b1e649","target":"record","created_at":"2026-07-05T08:53:13Z","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":"5c964443c4e6a8a88454cba35b8bf5762258825ef820de4e32ca866e49ca80c5","cross_cats_sorted":["cs.GR","eess.IV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2022-02-23T18:58:56Z","title_canon_sha256":"e65863528424871d36c8bf1aa04039da83293d03791ee5a3a4bf8d17c5852413"},"schema_version":"1.0","source":{"id":"2202.11703","kind":"arxiv","version":3}},"canonical_sha256":"c980202abbeb7c64703b878a42158fee2fbaa8b42c1cbc3c695893b0839d025d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c980202abbeb7c64703b878a42158fee2fbaa8b42c1cbc3c695893b0839d025d","first_computed_at":"2026-07-05T08:53:13.795825Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:53:13.795825Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rexdqQLjNINucMy3PQ1Hx05/4AUctk1kKxnSQL1lS/Q0vQoQMikERQEpHY5/bLbZnF41lEIT9E+OSMIuOZfBDw==","signature_status":"signed_v1","signed_at":"2026-07-05T08:53:13.796261Z","signed_message":"canonical_sha256_bytes"},"source_id":"2202.11703","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:76c7b36161d81cdcc2ea5bc85e177f7781766541a1548489307a0f7501b1e649","sha256:b0731af5ab90e6f89997b3e6fc86a064728da3725628997a1415c026c533a684"],"state_sha256":"a74c43174da14608d032a138323db17e5e5fdaab752a5e4ad0a28375158abb21"}
