However, it is difficult to make useful cameraworks by real camera controls automatically. In this paper, we propose a method to generate tracking image sequences with arbitrary cameraworks virtually from a tracking sequence taken by an active camera system. We decide the virtual view based on the viewing direction of the real tracking image, position and area of a tracked object on it, and position and area of the object on the virtual camerawork image. We use fixed-viewpoint pan-tilt-zoom camera and perspective projection, and show several experimental results with this method.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"20","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"11","bibliographicIssueDates":{"bibliographicIssueDate":"2003-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG09(CVIM7)","bibliographicVolumeNumber":"44"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:50:53.970790+00:00","updated":"2025-01-22T22:59:12.489625+00:00"}
