This paper presents a unified, simple, and effective framework for these essentially similar tasks. The framework, named K-Net, segments both instances and semantic categories consistently by a group of learnable kernels, where each kernel is responsible for generating a mask for either a potential instance or a stuff class. To remedy the difficulties of distinguishing various instances, we propose a kernel update strategy that enables each kernel ","authors_text":"Chen Change Loy, Jiangmiao Pang, Kai Chen, Wenwei Zhang","cross_cats":["cs.AI"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2021-06-28T17:18:21Z","title":"K-Net: Towards Unified Image Segmentation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2106.14855","kind":"arxiv","version":2},"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:eb05a981431aa404f2105b6055558ef70d0b66deae5e211849820d3f9e7d449c","target":"record","created_at":"2026-07-05T03:27:33Z","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":"4ff6c47bbf5958820bcbc0715d703baa19897117772abcae4f949556f18298b8","cross_cats_sorted":["cs.AI"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.CV","submitted_at":"2021-06-28T17:18:21Z","title_canon_sha256":"7059245383b5ae4c3172192cd0809febfa3939897f1b1ede3328ae488f22c72a"},"schema_version":"1.0","source":{"id":"2106.14855","kind":"arxiv","version":2}},"canonical_sha256":"3f1f4416e25f6cafbd65a1ea6cd73b51e0e5fdd7dc76cd9158028f3fe79e9114","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3f1f4416e25f6cafbd65a1ea6cd73b51e0e5fdd7dc76cd9158028f3fe79e9114","first_computed_at":"2026-07-05T03:27:33.183138Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:27:33.183138Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"p2sn3XOFE2P4uL/7QhW9sUeuyUI1Z8IU5Xrk89syQ999QPnLBM6mxy3c1doCCKtdXkSGvrZyOeqk2uVR/89NCw==","signature_status":"signed_v1","signed_at":"2026-07-05T03:27:33.183653Z","signed_message":"canonical_sha256_bytes"},"source_id":"2106.14855","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:eb05a981431aa404f2105b6055558ef70d0b66deae5e211849820d3f9e7d449c","sha256:b3e8851f5bfac402d5bb5e220045b6cbb2b55dd3a6664830bdcbb75118d125f7"],"state_sha256":"d8a4861ed80d33c2aebf115aea23187282d604d75098e39277f43a33ce078dd9"}
