Currently, splicing detection, copy-move detection and image retouching detection are drawing much attentions from researchers. However, image editing techniques develop with time goes by. One emerging image editing technique is colorization, which can colorize grayscale images with realistic colors. Unfortunately, this technique may also be intentionally applied to certain images to confound object recognition algorithms. To the best of our knowledge, no forensic technique has yet been invented to identify whether an image is ","authors_text":"Rui Wang, Wei Zhang, Xiaochun Cao, Yuanfang Guo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.MM","submitted_at":"2018-01-09T02:58:45Z","title":"Fake Colorized Image Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1801.02768","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:fcf5b33c185f358b1c69baf39da970514e24fef0f2e742fba8f39d2873539681","target":"record","created_at":"2026-05-18T00:23:04Z","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":"2b3b8356fd99e280dae53838218b46798df625f6e2163be4a5d5ae468db70078","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.MM","submitted_at":"2018-01-09T02:58:45Z","title_canon_sha256":"8c2fa8a672abc7bd14d9758736285bcf9c575fe1a24f87509d5694832020a49d"},"schema_version":"1.0","source":{"id":"1801.02768","kind":"arxiv","version":2}},"canonical_sha256":"d4cf9ad9d0ea4821ecd27c52220698dda2563d868a6aa105a42bce289d138193","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d4cf9ad9d0ea4821ecd27c52220698dda2563d868a6aa105a42bce289d138193","first_computed_at":"2026-05-18T00:23:04.984366Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:23:04.984366Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/LMyy8IRbf1LGb5nHZM0yCyj9B2k0/L2oz+49pH6fpnfHQkygvHeoUG3AXUgRKHlegjbfgTErW6GmHyUq35VAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:23:04.984937Z","signed_message":"canonical_sha256_bytes"},"source_id":"1801.02768","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fcf5b33c185f358b1c69baf39da970514e24fef0f2e742fba8f39d2873539681","sha256:902f081a9084342228d8f2a5f96b70416ec699fd077feb0bc125dcdba6d8220b"],"state_sha256":"25c90f3247398027cf9a3f26ec841c23571bf2ba627c315616abf6c3654570d0"}
