Recent studies attempted to exploit the potential of visual foundation models such as GroundingDINO. Despite the considerable progress, we observe certain shortcomings, including the limited diversity of visual prompts and suboptimal training regimen. \n\nTo address these issues, we introduce VQCounter, which incorporates a visual prompt queue mechanism designed to enrich the diversity of visual prompts. \n\nA random modality switching strategy is proposed during training to strengthen both textual and visual modalities. \n\nBesides, in light of weak point supervision, a Voronoi diagram-based cost (VoronoiCost) is designed to improve Hungarian matching, leading to more stable and faster convergence. \n\nBuilding upon the Voronoi diagram, we also propose a novel set of more stringent evaluation metrics, which take point localization into account. \n\nExtensive experiments on the FSC-147 and CARPK datasets demonstrate that VQCounter achieves state-of-the-art performance in both zero-shot and few-shot settings, significantly outperforming existing methods across nearly all evaluations.<\/jats:p>","DOI":"10.24963\/ijcai.2025\/252","type":"proceedings-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T08:10:40Z","timestamp":1758269440000},"page":"2260-2268","source":"Crossref","is-referenced-by-count":0,"title":["VQCounter: Designing Visual Prompt Queue for Accurate Open-World Counting"],"prefix":"10.24963","author":[{"given":"Fanfan","family":"Ye","sequence":"first","affiliation":[{"name":"Zhejiang University"},{"name":"Hikvision Research Institute"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiqi","family":"Fan","sequence":"additional","affiliation":[{"name":"Hikvision Research Institute"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiaoyong","family":"Zhong","sequence":"additional","affiliation":[{"name":"Hikvision Research Institute"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shicai","family":"Yang","sequence":"additional","affiliation":[{"name":"Hikvision Research Institute"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Di","family":"Xie","sequence":"additional","affiliation":[{"name":"Hikvision Research Institute"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Song","sequence":"additional","affiliation":[{"name":"Zhejiang University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mingli","family":"Song","sequence":"additional","affiliation":[{"name":"Zhejiang University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"number":"34","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-2025","name":"Thirty-Fourth International Joint Conference on Artificial Intelligence {IJCAI-25}","start":{"date-parts":[[2025,8,16]]},"theme":"Artificial Intelligence","location":"Montreal, Canada","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":"2025-09-23T11:33:28Z","timestamp":1758627208000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2025\/252"}},"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\/252","relation":{},"subject":[],"published":{"date-parts":[[2025,9]]}}}
