Particularly, deep learning-based super-resolution (SR) approaches have drawn much attention and have greatly improved the reconstruction performance on synthetic data. Recent studies show that simulation results on synthetic data usually overestimate the capacity to super-resolve real-world images. In this context, more and more researchers devote themselves to develop SR approa","authors_text":"Ce Zhu, Chao Ren, Honggang Chen, Linbo Qing, Xiaohai He, Yuanyuan Wu","cross_cats":["cs.CV"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.IV","submitted_at":"2021-03-03T12:41:44Z","title":"Real-World Single Image Super-Resolution: A Brief Review"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2103.02368","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":"sha256:7528e25714621706245775dac56d554adabc6b774fa8600d32feace29caf3c50","target":"record","created_at":"2026-07-05T02:20:03Z","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":"8ce2a7be7eee1ee085e612ada0636e8b6af1c27f01a436d496bf7761c4a2f0ea","cross_cats_sorted":["cs.CV"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.IV","submitted_at":"2021-03-03T12:41:44Z","title_canon_sha256":"5018f7d687677fedf18697c9e219a6191ced04752d39c91bd0ba9f8a3f2138bb"},"schema_version":"1.0","source":{"id":"2103.02368","kind":"arxiv","version":1}},"canonical_sha256":"507b217cbf01f7d6c0e7d90bd2f841a98c06b9b9f0cf8213f1c79838bb125900","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"507b217cbf01f7d6c0e7d90bd2f841a98c06b9b9f0cf8213f1c79838bb125900","first_computed_at":"2026-07-05T02:20:03.679729Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:20:03.679729Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"yun1hPas0Tw3hioy7gO6wJdkx/c5C2dd0kpK2STM1jvWfQQ2GS0dOG9fD4TpVaiSK9i0yRozJJw8aTonei8RDw==","signature_status":"signed_v1","signed_at":"2026-07-05T02:20:03.680134Z","signed_message":"canonical_sha256_bytes"},"source_id":"2103.02368","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7528e25714621706245775dac56d554adabc6b774fa8600d32feace29caf3c50","sha256:0d7d457de6ba2abba6bf2c69ad2e0314190ecf5039c62ff707a171be33bae8c1"],"state_sha256":"79a96ae47bd7cb3b98d8933f30663770bc3a610c52dbe66e762e34a5402b1aba"}
