However, because they borrow texture from their background and have a similar appearance to their surroundings, transparent objects are not handled well by regular image segmentation methods. We propose a method that overcomes these problems using the consistency and distortion properties of a light-field image. Graph-cut optimization is applied for the pixel labeling problem. The light-field linearity is used to estimate the likelihood of a pixel belonging to the transparent object or Lambertian backgr","authors_text":"Atsushi Shimada, Hajime Nagahara, Rin-ichiro Taniguchi, Yichao Xu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2015-11-21T08:33:18Z","title":"TransCut: Transparent Object Segmentation from a Light-Field Image"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.06853","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":"sha256:62820d35a623c27af482804fb2a8d0ae76ca04586090ac8cff62784715127b0c","target":"record","created_at":"2026-05-18T01:26:17Z","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":"135c46758b31773d9e1f5759c3ba4010bea300a81fc7d4af67e617b69497a717","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2015-11-21T08:33:18Z","title_canon_sha256":"c9aa60c4bdccc927e0eaf8cc6683afa9ab5952ffc4bd935eee92bdfb04c5fd82"},"schema_version":"1.0","source":{"id":"1511.06853","kind":"arxiv","version":1}},"canonical_sha256":"0fd29b35ce2dc9c340bab22d94ca1e0bf8aa06c7d6384bba64cac2068c1e7d45","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0fd29b35ce2dc9c340bab22d94ca1e0bf8aa06c7d6384bba64cac2068c1e7d45","first_computed_at":"2026-05-18T01:26:17.344500Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:26:17.344500Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JHuFWb9jcse+2X96pX90w5sNFWikvwae+vf0QKpkxEA47AwlSwSvqLpFZ/pCnuVxPcPjOzySluB9M81np3nMCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:26:17.345249Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.06853","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:62820d35a623c27af482804fb2a8d0ae76ca04586090ac8cff62784715127b0c","sha256:7221ffea90c03b4eabf1d1be43b226117d4c9a9a5adc07a94fc977a9e9c1d469"],"state_sha256":"a7643ef4f8b7bd4df79d2ce101a597856c91e502a2c6cf3ac41ee853800f02f8"}
