We study the dense keypoint regression framework that is previously inferior to the keypoint detection and grouping framework. Our motivation is that regressing keypoint positions accurately needs to learn representations that focus on the keypoint regions.\n  We present a simple yet effective approach, named disentangled keypoint regression (DEKR). We adopt adaptive convolutions through pixel-wise spatial transformer to activate the pixels in the keypoint regions and accordingly learn representa","authors_text":"Bin Xiao, Jingdong Wang, Ke Sun, Zhaoxiang Zhang, Zigang Geng","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2021-04-06T05:54:46Z","title":"Bottom-Up Human Pose Estimation Via Disentangled Keypoint Regression"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2104.02300","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":"sha256:3b632c9df10b9b9415b4796207bb1f365b03d4781efb5f5f212eca17b909fc01","target":"record","created_at":"2026-07-05T02:29:16Z","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":"3512f096f45249d96cf7368298bbcc569a9926ef68aec8e36c28edf4191699bd","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2021-04-06T05:54:46Z","title_canon_sha256":"e0f7d22a780e4ed16b7a7090089884b6bd67d2d80d803cd3e65d95a1cd91ce4f"},"schema_version":"1.0","source":{"id":"2104.02300","kind":"arxiv","version":1}},"canonical_sha256":"cff561ea478e69d9cb2334e3db0d7ac0c7b2d445eab6c3845181f31c31a67e87","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cff561ea478e69d9cb2334e3db0d7ac0c7b2d445eab6c3845181f31c31a67e87","first_computed_at":"2026-07-05T02:29:16.827429Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:29:16.827429Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wmgn35G7QasAyOPBgHdGLLvc1ubW9g4Dv5TV7sPdr2H7pO2oNhQJ2tH2LAzw0zBF1/B8GG+6jLEiA6grp5XTBA==","signature_status":"signed_v1","signed_at":"2026-07-05T02:29:16.827856Z","signed_message":"canonical_sha256_bytes"},"source_id":"2104.02300","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3b632c9df10b9b9415b4796207bb1f365b03d4781efb5f5f212eca17b909fc01","sha256:2486b3d813d10ea4409caff32e763ac9d5e124f84fa33dda7a51b24452ebad3a"],"state_sha256":"e8cddad7ab568340739d7bc2d398f1747033e2bb54b9b15740a75e859667b296"}
