Detecting the presence of clouds -- which is increasingly done using deep learning -- is crucial preprocessing in EO applications. In fact, advanced EO satellites perform deep learning-based cloud detection on board the satellites and downlink only clear-sky data to save precious bandwidth. In this paper, we highlight the vulnerability of deep learning-based cloud detection towards adversarial attacks. By optimising an adversarial pattern and superimposing it into a cloudless scene, we bias the neural network","authors_text":"Andrew Du, Bo Chen, Ken Clarke, Michael Brown, Michele Sasdelli, Tat-Jun Chin, Yee Wei Law","cross_cats":["eess.IV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2021-12-03T05:27:50Z","title":"Adversarial Attacks against a Satellite-borne Multispectral Cloud Detector"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2112.01723","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:d81e5e732fee95699b0f1d05077f5d5abe9115517532992dcb698961b982e09b","target":"record","created_at":"2026-07-05T03:37:31Z","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":"87656424969db34279bb652e5ad9dffb109ff929894c36df3306dd6598c89d9c","cross_cats_sorted":["eess.IV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2021-12-03T05:27:50Z","title_canon_sha256":"a60c4710c4bddf1f85a91c5cf91173edb3ad7b6534090d9b17ee66f2190c6251"},"schema_version":"1.0","source":{"id":"2112.01723","kind":"arxiv","version":1}},"canonical_sha256":"a90451ff9693e851b149911674a415a6b18d26ce79837315ddbfbd4e588dce4d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a90451ff9693e851b149911674a415a6b18d26ce79837315ddbfbd4e588dce4d","first_computed_at":"2026-07-05T03:37:31.482013Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:37:31.482013Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NvcyD1iikLrJFfV1tBKFrLHwbseL55l8Ab0mnUILjXXiWWTPeEo6/4P8iOrCdjna0KhUA5iZ6e5otsF8HHINCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T03:37:31.482510Z","signed_message":"canonical_sha256_bytes"},"source_id":"2112.01723","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d81e5e732fee95699b0f1d05077f5d5abe9115517532992dcb698961b982e09b","sha256:65d4e78e9485985fb9e9bfeccf80449fa7b2c5b1fcdcd23910352a61a3d58388"],"state_sha256":"ddff02b7225ff64de7b57f92d8eb3049d078663eff4ce0064d37b6e7e2462167"}
