In a 'plain' VVC approach, concepts from picture-to-picture temporal prediction are employed for decorrelation along the MSI's spectral dimension. The popular principle component analysis (PCA) for spectral decorrelation is further evaluated in combination with VVC intra-coding for spatial decorrelation. This approach is referred to as PCA-VVC. A novel adaptive MSI compression algorithm, named HPCLS, is introduced, that uses PCA and inter-prediction for spectral and VVC ","authors_text":"Mathias Wien, Philipp Seltsam, Priyanka Das","cross_cats":["cs.MM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.IV","submitted_at":"2023-01-10T18:37:47Z","title":"Adaptive and Scalable Compression of Multispectral Images using VVC"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2301.04117","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":"sha256:12bb643dd1cb1384c46d0c0f41affd1114adf16684e18f3602205079683c1e20","target":"record","created_at":"2026-07-05T05:32:10Z","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":"13c7cef8a2441294681b95b32633dce00868ddd960481f5e77eee67b64f3b388","cross_cats_sorted":["cs.MM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.IV","submitted_at":"2023-01-10T18:37:47Z","title_canon_sha256":"e1c3a2bba92634bfb96cb8ea6af890c0fcbdd2f8534ab011146396a7645146cc"},"schema_version":"1.0","source":{"id":"2301.04117","kind":"arxiv","version":1}},"canonical_sha256":"c80721453b24c7d42094a8fa39b75e2f92b29ea4a3c9a985a6d208ef541ef458","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c80721453b24c7d42094a8fa39b75e2f92b29ea4a3c9a985a6d208ef541ef458","first_computed_at":"2026-07-05T05:32:10.393985Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:32:10.393985Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9E9F7atLVvOGTPVhkHfvJpVy0LcpSGB9y2kxz7k8nzXA9odYlaXQRmQp3j8AtExBLDuYKFBAqkhT72D8rHF1AQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:32:10.394501Z","signed_message":"canonical_sha256_bytes"},"source_id":"2301.04117","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:12bb643dd1cb1384c46d0c0f41affd1114adf16684e18f3602205079683c1e20","sha256:84c5e5406e1a5b137df96be509769859bdec70b6ffa007e46c98bb7ed212b5c2"],"state_sha256":"6b078acedf8a0a3ea9333ce50dc89fb436ead860ad912ee9dc45ed016e8ee025"}
