In addition, our proposed method can restrain scene flicker effectively, and there is no incongruity in the output video.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"45","bibliographic_titles":[{"bibliographic_title":"情報処理学会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":"39","bibliographicIssueDates":{"bibliographicIssueDate":"2002-03-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"26(2001-CVIM-132)","bibliographicVolumeNumber":"2002"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":52734,"updated":"2025-01-22T06:38:23.844865+00:00","links":{},"created":"2025-01-18T23:16:59.708823+00:00"}
