Recently proposed trainable nonlinear reaction diffusion (TNRD) model defines a simple but very effective framework for image denoising. However, as the TNRD model is a local model, the diffusion behavior of which is purely controlled by information of local patches, it is prone to create artifacts in the homogenous regions and over-smooth highly textured regions, especially in the case of strong noise levels. Meanwhile, it is widely known that the non-local self-similarity (NSS) prior stands as an effective image prior ","authors_text":"Peng Qiao, Wensen Feng, Yong Dou, Yunjin Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-02-24T06:12:55Z","title":"Learning Non-local Image Diffusion for Image Denoising"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.07472","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":"sha256:9ac5dd651442d680b9a1cc5e1bd9046c5b7df5baac577aba63cdb79ed1e395d4","target":"record","created_at":"2026-05-18T00:50:03Z","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":"046dede43c15822858ae96877e5c5478c0608f76407ec720cb7cb63f4c1b8947","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-02-24T06:12:55Z","title_canon_sha256":"f86eb691e0603977fbbd961523122572e59e4aa1018dc3e768fb98a85d503a1a"},"schema_version":"1.0","source":{"id":"1702.07472","kind":"arxiv","version":1}},"canonical_sha256":"bdc87806dd48b4e68fdc08f95e106a070064d77347ff09e05ab6d73501c977f4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bdc87806dd48b4e68fdc08f95e106a070064d77347ff09e05ab6d73501c977f4","first_computed_at":"2026-05-18T00:50:03.242530Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:50:03.242530Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WLYXByXdiE3+O7JaVntVdKDQShBMoFT0DFdkfLnH3t6ktwbRmJIv+2BqNrSAh9cqBxhbOSjWFSQvew/PBYCbCw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:50:03.243190Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.07472","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9ac5dd651442d680b9a1cc5e1bd9046c5b7df5baac577aba63cdb79ed1e395d4","sha256:6683c68bde243b841654cdfeb5aec8682216cae1dd7f54b4d7afc1c5a868dc64"],"state_sha256":"d0189da8b329f5efdb1775bb1d6a92d99aac0cfe62769beec2ce5e864bb16823"}
