We find that one of the main reasons for that is the lack of an effective receptive field in both the inpainting network and the loss function. To alleviate this issue, we propose a new method called large mask inpainting (LaMa). LaMa is based on i) a new inpainting network architecture that uses fast Fourier convolutions (FFCs), which have the image-wide receptive field; ii) a high receptive field perceptual loss; iii) large trai","authors_text":"Aleksei Silvestrov, Anastasia Remizova, Anton Mashikhin, Arsenii Ashukha, Elizaveta Logacheva, Harshith Goka, Kiwoong Park, Naejin Kong, Roman Suvorov, Victor Lempitsky","cross_cats":["eess.IV"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2021-09-15T08:54:29Z","title":"Resolution-robust Large Mask Inpainting with Fourier Convolutions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2109.07161","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:e19669c18e409f2e55445e235bdc64c8656c99d2fa67d1e0f9f0a52c1575dd21","target":"record","created_at":"2026-07-05T03:30:54Z","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":"45188ca95d5b29579f2b5d2e73838e647f5d547b8ab81f0794114038b076ff0a","cross_cats_sorted":["eess.IV"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2021-09-15T08:54:29Z","title_canon_sha256":"11a05583a9d6898214d758f05047cb19111aff5ddc3ee4bd3cbb1d4855558db2"},"schema_version":"1.0","source":{"id":"2109.07161","kind":"arxiv","version":2}},"canonical_sha256":"5400cdb857274d4049e866d9513993b6361b58b054ab81c6d5fc41362e2d924f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5400cdb857274d4049e866d9513993b6361b58b054ab81c6d5fc41362e2d924f","first_computed_at":"2026-07-05T03:30:54.125293Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:30:54.125293Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"OZY7GhgIKja9AyHg8/fGbNuGXCJAAFh1112nb/06OEUwKhhAPDEWX9ywAg92YGgST2lq1ssbVgDbV+9VH8EfAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T03:30:54.125802Z","signed_message":"canonical_sha256_bytes"},"source_id":"2109.07161","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e19669c18e409f2e55445e235bdc64c8656c99d2fa67d1e0f9f0a52c1575dd21","sha256:d46b125b0450588243733b05d99981934455ccb14535590e0def5db8dd4dafb6"],"state_sha256":"710190bdec393d10aa148e29705245348f2d71344457ed97b806258f23b7a799"}
