Many recent works have shown that a two-stage approach, which first detects keypoints and then solves a Perspective-n-Point (PnP) problem for pose estimation, achieves remarkable performance. However, most of these methods only localize a set of sparse keypoints by regressing their image coordinates or heatmaps, which are sensitive to occlusion and truncation. Instead, we introduce a Pixel-wise Voting Network (PVNet) to regress pixel-wise unit vectors pointing to the keypoin","authors_text":"Hujun Bao, Qixing Huang, Sida Peng, Xiaowei Zhou, Yuan Liu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-12-31T13:24:10Z","title":"PVNet: Pixel-wise Voting Network for 6DoF Pose Estimation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.11788","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":"sha256:26ab86ec19faeb753526056d2f65c20238b95ad524d5c1c1661669bd0c286955","target":"record","created_at":"2026-05-17T23:57:11Z","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":"220429fc35dcbb8b32914177c2c0030caf5b3df7151072711ca535630273fbdf","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-12-31T13:24:10Z","title_canon_sha256":"af1cd35fbb61ac04928acbfba33aa97c855dbedf0d9f849fcb9ab11ddd933bdc"},"schema_version":"1.0","source":{"id":"1812.11788","kind":"arxiv","version":1}},"canonical_sha256":"c3daef10960d7e7854c8c0c480941b433c6d166d3679460ff05aed554158ecb0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c3daef10960d7e7854c8c0c480941b433c6d166d3679460ff05aed554158ecb0","first_computed_at":"2026-05-17T23:57:11.134229Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:57:11.134229Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"j7uWaVXvd6GzGqIRXrM7rAEy6KK0I6q9Cpzf6yfDWUL/x/peu1uGGB5F5hg792d42JUohy5r+eqLuLd4coQfCg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:57:11.134603Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.11788","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:26ab86ec19faeb753526056d2f65c20238b95ad524d5c1c1661669bd0c286955","sha256:81f35efe4902375d01d70d6d32e73e222e6be676663250e9e771dde852195e6a"],"state_sha256":"3a3582c20d9b66d8c0cc3e2de4a3fe531d8a2c0c5d7ec991a22e92319a2d9c87"}
