(Quality of View,QoV) が低下する.そこで我々は,組み合わせ最適化の手法で,最短経路問題で広く用いられるダイクストラ法をこの問題に応用し,一定時間カメラの切り替えが行われず,動画全体で観測している術野領域が最大になるカメラスケジューリング手法を提案する.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","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":"2019-01-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"18","bibliographicVolumeNumber":"2019-CVIM-215"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T00:58:58.959110+00:00","id":193843,"links":{}}
