However, while a large body of work has focused on learning visual correspondences at the pixel-level, few approaches have emerged to learn correspondence at the level of line enclosures (segments) that naturally occur in hand-drawn animation. Exploiting this structure in animation has numerous benefits: it avoids the intractable memory complexity of attending to individual pixels in high resolution images and enables the use of real-world animation datasets that contain corre","authors_text":"Evan Casey, Harry Teitelman, Mike Manh, Nick Boyajian, Tim Pulver, V\\'ictor P\\'erez, William Grisaitis, Zhuoru Li","cross_cats":["cs.AI","cs.GR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2021-09-06T17:23:40Z","title":"The Animation Transformer: Visual Correspondence via Segment Matching"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2109.02614","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:abac30b42b344d1b846b3b9a62b38c7fb099b161747fb2dd183a08e62a839437","target":"record","created_at":"2026-07-05T03:12:28Z","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":"e8be0533c98ff320b2d5da3f4f7f5e55c3f2dd20732a0587371bac6c8020ab5c","cross_cats_sorted":["cs.AI","cs.GR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2021-09-06T17:23:40Z","title_canon_sha256":"93e4539f4eafa7e4d2aa8f516f23b396827a290ca68d0c7fa2e4634046c9d289"},"schema_version":"1.0","source":{"id":"2109.02614","kind":"arxiv","version":2}},"canonical_sha256":"c49309fdf0dfea8b7154a5ca7258ce3e8d471640b1a59b16c36c32df5a211663","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c49309fdf0dfea8b7154a5ca7258ce3e8d471640b1a59b16c36c32df5a211663","first_computed_at":"2026-07-05T03:12:28.865971Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:12:28.865971Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"46P0m1tM6j68X/tMlFlF3AGePQ8vzloTdlAH48CFWeBFXL4vaA80DDlC1SNhmt2wAFTzXTTyTl1w4YcYWYCDAA==","signature_status":"signed_v1","signed_at":"2026-07-05T03:12:28.866381Z","signed_message":"canonical_sha256_bytes"},"source_id":"2109.02614","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:abac30b42b344d1b846b3b9a62b38c7fb099b161747fb2dd183a08e62a839437","sha256:77ffd6534642271700ccbd07f6b173d2a44d7253621e2d2025704b69d6158460"],"state_sha256":"e1fea5551fc0d90343a0cb0599c9faedb1c21fe5f9646aaf5a7304293d2c20a0"}
