Several CS reconstruction models have been proposed and obtained superior performance. However, these methods suffer from blocking artifacts or ringing effects at low sampling ratios in most cases. To address this problem, we propose a deep convolutional Laplacian Pyramid Compressed Sensing Network (LapCSNet) for CS, which consists of a sampling sub-network and a reconstruction sub-network. In the sampling sub-network, we utilize a convoluti","authors_text":"Debin Zhao, Feng Jiang, Heyao Xu, Shengping Zhang, Wenxue Cui, Xinwei Gao","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-04-13T14:42:20Z","title":"An efficient deep convolutional laplacian pyramid architecture for CS reconstruction at low sampling ratios"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.04970","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:e0beb3f240735de9e6abce7ba23f51c114f849f1fe4811ae7f2f331b2e6bcffd","target":"record","created_at":"2026-05-18T00:18:32Z","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":"7e134172b986194274bd79bddfaf90813e26568dfa3eac0fef4bdfbc734125e6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-04-13T14:42:20Z","title_canon_sha256":"c32b1219ba6e53a5edc12c0328beb87bd7b2010733e7b447f4f5c4d4ca1e7ebd"},"schema_version":"1.0","source":{"id":"1804.04970","kind":"arxiv","version":1}},"canonical_sha256":"e590816cbef8fad8bda432c18c8d383566319a61ea06966cb8e376f2a442ee41","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e590816cbef8fad8bda432c18c8d383566319a61ea06966cb8e376f2a442ee41","first_computed_at":"2026-05-18T00:18:32.558194Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:18:32.558194Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QfxzBRLG9SutsZRtDMweO2MBVKO1wUMKpYVU8BeYaBFdHaqgNz4/ZNRv3SFiNKeL8fEV9A9HarjTZSZLnCrkBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:18:32.558630Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.04970","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e0beb3f240735de9e6abce7ba23f51c114f849f1fe4811ae7f2f331b2e6bcffd","sha256:02e5ebc39aa25e9444df2f555da066c73a3e986c8fc84497939b231ef1597448"],"state_sha256":"53f3daae03d955c5fdbf2a7e18216356d0124ca8dc5c2461c6c0d92effcf38b6"}
