Despite the progress, efficient and accurate end-to-end spotting of arbitrarily-shaped text remains challenging. In this work, we propose an end-to-end text spotting framework, termed PAN++, which can efficiently detect and recognize text of arbitrary shapes in natural scenes. PAN++ is based on the kernel representation that reformulates a text line as a text kernel (central region) surrounded by peripheral pixels. By systematically comparing with existing scene text representations, we show that our kernel rep","authors_text":"Chunhua Shen, Ding Liang, Enze Xie, Tong Lu, Wenhai Wang, Xiang Li, Xuebo Liu, Zhibo Yang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2021-05-02T07:04:30Z","title":"PAN++: Towards Efficient and Accurate End-to-End Spotting of Arbitrarily-Shaped Text"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2105.00405","kind":"arxiv","version":4},"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":"sha256:60324433235cbec94f71018b46d508172835686f87fc9c99cf85d72281685a55","target":"record","created_at":"2026-07-05T03:02:15Z","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":"f94a140106f168e54579a44c893d586208064189285050a7ff4cd83fb4736b24","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2021-05-02T07:04:30Z","title_canon_sha256":"376883459f28efcc33788c1229a8eb1dff1b662897306312153c8996199070ef"},"schema_version":"1.0","source":{"id":"2105.00405","kind":"arxiv","version":4}},"canonical_sha256":"5003c75d925a92275c5990e3cc9df2df317aef3bf0626d334b4c2b7b70ba3738","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5003c75d925a92275c5990e3cc9df2df317aef3bf0626d334b4c2b7b70ba3738","first_computed_at":"2026-07-05T03:02:15.478728Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:02:15.478728Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1XQDDuq0kLTTxf54Egjye5Hzw5pJa6CG9JzjEXBKIpAvwkJBgqBQ7UQ0JPLMSGcBwKHOdjXAhLgdOapL9qwdAw==","signature_status":"signed_v1","signed_at":"2026-07-05T03:02:15.479158Z","signed_message":"canonical_sha256_bytes"},"source_id":"2105.00405","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:60324433235cbec94f71018b46d508172835686f87fc9c99cf85d72281685a55","sha256:f068a56debffdb2207acbab76770c147b940e771abc598cde0a3560026d16130"],"state_sha256":"d75d9dc9d2b80ebc78739d2742ce2496beaf83bcd3c3b639bdf6467b86a36b09"}
