The proposed technique is a soft-computing approach, based on the concept of rough set with rough clustering and Pawlak's accuracy. It is less noisy and avoids pre-deterministic knowledge about the distribution of the changed and unchanged regions. To show the effectiveness, the proposed technique is compared with some other approaches.","authors_text":"Chandranath Adak","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2014-04-24T10:09:41Z","title":"Rough Clustering Based Unsupervised Image Change Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1404.6071","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":"sha256:5148d797d6762e7df1308abff32346c538490a136f8ed23ccce37646548aac8a","target":"record","created_at":"2026-05-18T02:53:18Z","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":"79ba829d09f0b5ee5436a10c73f11225bd86c6bd3780e6d6aeac8662b9925993","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2014-04-24T10:09:41Z","title_canon_sha256":"8a721e07d5d200889c4d989d28982ee3afa76c040b9755f9aff3c7cc126f2e2c"},"schema_version":"1.0","source":{"id":"1404.6071","kind":"arxiv","version":1}},"canonical_sha256":"afdba4c52a31b20a962ecc5d953b3aed53454131eb7513110b039b003fa8afa9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"afdba4c52a31b20a962ecc5d953b3aed53454131eb7513110b039b003fa8afa9","first_computed_at":"2026-05-18T02:53:18.443713Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:53:18.443713Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zd742o9bah0HC2kSdPMH4w28ct83eIWdmI2oGVIV32D8RFYwpf/MVdgiD9qCyiObwW95J56gxZyPyYB+hhweAg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:53:18.444383Z","signed_message":"canonical_sha256_bytes"},"source_id":"1404.6071","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5148d797d6762e7df1308abff32346c538490a136f8ed23ccce37646548aac8a","sha256:486a98bd01f030edf17418b28e586f1abc7d915ffe65ad866fd3bf2f7fb73efd"],"state_sha256":"4e779d037ce843b62f2bf390ded5ec57795b90ee56ac9f2ab9b64e47ff3d7055"}
