Recent studies benefiting from generative adversarial network (GAN) have promoted the development of SISR by recovering photo-realistic images. However, there are always undesired structural distortions in the recovered images. In this paper, we propose a structure-preserving super resolution method to alleviate the above issue while maintaining the merits of GAN-based methods to generate perceptual-pleasant details. Specifically, we exploit gradient maps of images to guide the recovery in two aspects. On the one hand, we restore high-","authors_text":"Ce Chen, Cheng Ma, Jie Zhou, Jiwen Lu, Yean Cheng, Yongming Rao","cross_cats":["cs.CV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.IV","submitted_at":"2020-03-29T17:26:58Z","title":"Structure-Preserving Super Resolution with Gradient Guidance"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2003.13081","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":"sha256:3f738d05650ed10e41ac2ce858649b162ce80288a6d558c985c98fc29c46b095","target":"record","created_at":"2026-07-05T00:51:21Z","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":"e7f63a09badd3921c004c0791e45af3a01600b258c95c5ada15a01973aa4bfd5","cross_cats_sorted":["cs.CV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.IV","submitted_at":"2020-03-29T17:26:58Z","title_canon_sha256":"7aed76a5aa310570dd2c4220d99561469eebf8c8dff64f9af2ec6a4bc177a87e"},"schema_version":"1.0","source":{"id":"2003.13081","kind":"arxiv","version":1}},"canonical_sha256":"d3721a0359e58b31fb87e668e161448392cf43f1edac3dfd45b3597045510c1b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d3721a0359e58b31fb87e668e161448392cf43f1edac3dfd45b3597045510c1b","first_computed_at":"2026-07-05T00:51:21.973035Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:51:21.973035Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6KlVgYPN9yftXLjueRqY1XQ6DJXE+iskpN7r21Rk2ftrUF1d7qKMZR7XxSo/9HYa2djFffhho8+xAVnX4cH0Cg==","signature_status":"signed_v1","signed_at":"2026-07-05T00:51:21.973462Z","signed_message":"canonical_sha256_bytes"},"source_id":"2003.13081","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3f738d05650ed10e41ac2ce858649b162ce80288a6d558c985c98fc29c46b095","sha256:5c9ef82331ad3f8fed274058a311becb6dbda407de1b05888a0f789ab8ddbfe6"],"state_sha256":"a8fb9ee99869c6ee2dba2f955fb1ad8e5e9ac8bdc026b4c9a9c2ad723de71fc5"}
