Input data include RGB-D images acquired from a Kinect camera and a 3D model of the hand constructed from its anatomy and graphical matrices. A cost function is then defined so that its minimum value is achieved when the model and observation images are matched. To solve the optimization problem in 26 dimensional space, the particle swarm optimization algorimth with improvements are used. In addition, parallel computation in graphical processing units (GPU) is utilized to handle computati","authors_text":"Anh Viet Dang, Cong Hoang Quach, Dinh Tuan Pham, Manh Duong Phung, Minh Trien Pham, Thuan Hoang Tran","cross_cats":["eess.IV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2020-05-13T08:05:30Z","title":"Recognition of 26 Degrees of Freedom of Hands Using Model-based approach and Depth-Color Images"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2005.07068","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":"sha256:78d523f56fc9f6598e4db85a13c344eecaa0a056974cb272ee3993463d16d075","target":"record","created_at":"2026-07-05T01:02:53Z","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":"fdf8070988a93881b11f6499c71eea3ccab901a13008fa1edf4a3c9f2b914c3d","cross_cats_sorted":["eess.IV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2020-05-13T08:05:30Z","title_canon_sha256":"1f1be49cf21d25e8072f4253f75f1292c6c1e690118f514283d350b2a449cb8d"},"schema_version":"1.0","source":{"id":"2005.07068","kind":"arxiv","version":1}},"canonical_sha256":"e5695184144c2fb3ba5633fc98cc9a6ed9e4168e52c0e5ef3ff9e12633355f7f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e5695184144c2fb3ba5633fc98cc9a6ed9e4168e52c0e5ef3ff9e12633355f7f","first_computed_at":"2026-07-05T01:02:53.000469Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:02:53.000469Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TalBeY5X2V2bg1xIG4qoic7wUiWfIyn0kvmXWA4CGqbuprGi7bV4a4RuUJK6Jnj/fBW7hpEuDbtoITZIQ0FsBg==","signature_status":"signed_v1","signed_at":"2026-07-05T01:02:53.000807Z","signed_message":"canonical_sha256_bytes"},"source_id":"2005.07068","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:78d523f56fc9f6598e4db85a13c344eecaa0a056974cb272ee3993463d16d075","sha256:821d0897c3f4347a241640d7bf64157dc64cdf6f1b96873d7fb1ec1be05421d0"],"state_sha256":"2e158b3aeb895f5fb3d9b3b712eb723205d34ad4bf57b5b526991c2b526a5321"}
