Existing approaches typically rely on additional reference information to mitigate these issues, however, customized data collection equipment poses limitations on their scalability. To alleviate the issue, we construct a Low-Light Images and Poses (LLIP) dataset, which includes only paired low-light images and pose annotations obtained using off-the-shelf motion capture devices. Furthermore, we propose a Multi-grained High-frequency Feature Consistency Learning framework (MHFCL), which does not rely on additional reference information. MHFCL employs a Retinex-inspired restoration stream to recover high-frequency details and integrates them into pose estimation using a multi-grained consistency mechanism. Experiments demonstrate that our approach achieves a new benchmark in low-light pose estimation, while maintaining competitive performance in well-lit conditions.<\/jats:p>","DOI":"10.24963\/ijcai.2025\/210","type":"proceedings-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T08:10:40Z","timestamp":1758269440000},"page":"1882-1890","source":"Crossref","is-referenced-by-count":9,"title":["Coming Out of the Dark: Human Pose Estimation in Low-light Conditions"],"prefix":"10.24963","author":[{"given":"Yong","family":"Su","sequence":"first","affiliation":[{"name":"Tianjin Normal University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Defang","family":"Chen","sequence":"additional","affiliation":[{"name":"Tianjin Normal University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meng","family":"Xing","sequence":"additional","affiliation":[{"name":"University of Science and Technology of China"},{"name":"Ningbo Institute of Digital Twin, Eastern Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changjae","family":"Oh","sequence":"additional","affiliation":[{"name":"Queen Mary University of London"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuewei","family":"Liu","sequence":"additional","affiliation":[{"name":"Research & Development Branch, FAW Toyota Motor Co.,Ltd."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jieyang","family":"Li","sequence":"additional","affiliation":[{"name":"Tianjin Normal University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10584","event":{"name":"Thirty-Fourth International Joint Conference on Artificial Intelligence {IJCAI-25}","theme":"Artificial Intelligence","location":"Montreal, Canada","acronym":"IJCAI-2025","number":"34","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"start":{"date-parts":[[2025,8,16]]},"end":{"date-parts":[[2025,8,22]]}},"container-title":["Proceedings of the Thirty-Fourth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T11:33:18Z","timestamp":1758627198000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2025\/210"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2025,9]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2025\/210","relation":{},"subject":[],"published":{"date-parts":[[2025,9]]}}}
