The micro-gesture classification task aims at recognizing the action category of a given video based on the skeleton data. For this task, we propose a 3D-CNNs-based micro-gesture recognition network, which incorporates a skeletal and semantic embedding loss to improve action classification performance. Finally, we rank 1st in the Micro-gesture Classification Challenge, surpassing the second-place team in terms of Top-1 accuracy by 1.10%.","url_abs":"https://arxiv.org/abs/2307.10624v1","url_pdf":"https://arxiv.org/pdf/2307.10624v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"joint-skeletal-and-semantic-embedding-loss","repo_url":"https://github.com/VUT-HFUT/MiGA2023_Track1","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"pytorch","reach":null}],"tasks":[{"task_slug":"action-classification","task_name":"Action Classification"},{"task_slug":"classification-1","task_name":"Classification"},{"task_slug":"gesture-recognition","task_name":"Gesture Recognition"},{"task_slug":"micro-gesture-recognition","task_name":"Micro-gesture Recognition"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/micro-gesture-recognition-on-imigue","task":"Micro-gesture Recognition","dataset":"iMiGUE","model":"","rank_in_archive_order":1,"of":1,"metrics":{"Top 1 Accuracy":"64.12","Top 5 Accuracy":"91.1"},"uses_additional_data":false}],"syntology":{"syntology_url":null,"atlas_url":"https://app.syntology.ai/?focus=2307.10624","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
