However, developments on hyperspectral imaging systems enable us to obtain redundant spectral information of the observed scenes from the reflected light source from objects. A few studies using low-level features on hyperspectral images demonstrated that salient object detection can be achieved. In this work, we proposed a salient object detection model on hyperspectral images by applying manifold ranking (MR) on self-s","authors_text":"Asako Kanezaki, Guanqun Ding, Nevrez Imamoglu, Ryosuke Nakamura, Toru Kouyama, Yuming Fang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2019-02-28T10:23:00Z","title":"Salient object detection on hyperspectral images using features learned from unsupervised segmentation task"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.10993","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":"sha256:5c925b25e84229a8e8adaa8dae7a14af49a8c61c98cef823de2a60a434c4c10f","target":"record","created_at":"2026-05-17T23:52:26Z","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":"0f5366c269b359b0244d3656a0cfbfca38bc94dac4d85cd53701adda58e01cce","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2019-02-28T10:23:00Z","title_canon_sha256":"50f541263abfafc1d528e51d217fb76d9e624e1887509770405051374b9f29d7"},"schema_version":"1.0","source":{"id":"1902.10993","kind":"arxiv","version":1}},"canonical_sha256":"946d49852aa29bf6959eb6cd610a7d89d9964a0f6a046cd918730b854cb449df","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"946d49852aa29bf6959eb6cd610a7d89d9964a0f6a046cd918730b854cb449df","first_computed_at":"2026-05-17T23:52:26.160753Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:52:26.160753Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AzqXvLwbe/VkwZsFAEygEOVk5cnjPs7aIz086TqFAu9DIKonKYdZ/XoA+qlHTCRsRGrqgGGfmpOC2rdBn33CBg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:52:26.161390Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.10993","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5c925b25e84229a8e8adaa8dae7a14af49a8c61c98cef823de2a60a434c4c10f","sha256:9d716d388abefa0503eeb77a74c210c9513dc66d15165d880905ce48d2f47e6b"],"state_sha256":"56475ffb9b694034129ba101f2089aafe6603ab6a34fe2d1490cff5d1f52797e"}
