Computer-aided nuclei grading aims to improve pathologists' work efficiency while reducing their misdiagnosis rate by automatically identifying the grades of tumor nuclei within histopathological images. Such a task requires precisely segment and accurately classify the nuclei. However, most of the existing nuclei segmentation and classification methods can not handle the inter-class similarity property of nuclei grading, thus can not be di","authors_text":"Chen Li, Chunbao Wang, Deyu Meng, Haichuan Zhang, Jialun Wu, Jiangbo Shi, Xianli Zhang, Yang Li, Zeyu Gao","cross_cats":["cs.CV"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.IV","submitted_at":"2021-06-20T07:32:26Z","title":"Nuclei Grading of Clear Cell Renal Cell Carcinoma in Histopathological Image by Composite High-Resolution Network"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2106.10641","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:f8c64a978642d6133e617ba15f0dad944350bc00f3f3fa25e34dfeeab9ed7f79","target":"record","created_at":"2026-07-05T02:50:51Z","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":"b9b75e03eaf02793c17c7603e47bfab0238e65ac9f1c0b764d82aedb5c5bf15b","cross_cats_sorted":["cs.CV"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.IV","submitted_at":"2021-06-20T07:32:26Z","title_canon_sha256":"f773d2f65628fecfd200b2466f7f4a19c94db3630c4de3124c376ec479b894ab"},"schema_version":"1.0","source":{"id":"2106.10641","kind":"arxiv","version":1}},"canonical_sha256":"38f9e1106ff9f5d27e13862ed145a64d9a3ac44814d2d630c09885920941d0e7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"38f9e1106ff9f5d27e13862ed145a64d9a3ac44814d2d630c09885920941d0e7","first_computed_at":"2026-07-05T02:50:51.514897Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:50:51.514897Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qZYMMc7+IVu0pAnAvEusch4fA+j5tgibStM+cVXdxWww67frPtXgJmrwt/lbT0W6tewZgXPUff+e7esbei1JAw==","signature_status":"signed_v1","signed_at":"2026-07-05T02:50:51.515237Z","signed_message":"canonical_sha256_bytes"},"source_id":"2106.10641","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f8c64a978642d6133e617ba15f0dad944350bc00f3f3fa25e34dfeeab9ed7f79","sha256:a1510d93d0cbfe19f5f93bf21ffab381f1b2b69a7c811ef9725c58677a48dc72"],"state_sha256":"fe2842d07a5f89589167108988a746d82b5ed9f2df2d1c3c7600fac90e066f28"}
