Considering feasibility for amateur use, the bat's position must be detected from images captured by inexpensive cameras. However, detecting the bat's position becomes challenging due to strong motion blur that occurs in frames where the bat moves at high speed. To address this, we propose a learning-based method that interpolates the bat's position in undetected frames based on detected frames. A Transformer-based model is employed, which uses the detection results of the bat as input and considers temporal information to estimate the bat's position in undetected frames. Experimental results demonstrate that the proposed method improves swing trajectory estimation accuracy compared to simple curve interpolation methods.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2025-01-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"22","bibliographicVolumeNumber":"2025-CVIM-240"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
