(1)被写体の取り違え(誤報)をゼロにしたい ・誤報は対象の人生を変えてしまう可能性があるなど, 社会的な影響が大きい. ・どんなに厳重に確認してもまれにミスが発生してし まうことがある. (2)被写体確認作業を効率化し迅速に報道したい ・人によるダブル,トリプル,それ以上のチェックを 行っており,非常に手間がかかる. ・紙資料やWEBで人の顔を確認するので1人あたり数 十秒以上かかってしまう.(仮に誰だか見当もつかな い場合,数十分以上かかることもある.) ・確認が間に合わずVTRがOAできないこともある. 「AI顔認識」技術(シーズ) 一方で,昨今の「AI顔認識」技術の進化は目覚ましい. 「AI顔認識」とは認識させたい人物の顔画像を事前に辞書 データベースに登録しておくことで,入力された映像に 映っている被写体が誰であるかを自動で認識させることが できる技術であり,PC・スマートフォンのログイン,空港 での入国審査,小売店での万引き防止,イベントでの入場 ゲートにおける本人確認など,多種多様な用途で利用され るようになってきている. そこで今回,上記のニーズとシーズを組み合わせ,テレ ビ番組の制作支援と作業効率化を目指した「AI顔認識シス テム」を開発するに至った.また,当該システムを「2019参 議院選挙特番」,「即位礼特番」,「ラグビーW杯」などの実 際の番組制作現場で活用している.","PeriodicalId":39325,"journal":{"name":"Kyokai Joho Imeji Zasshi/Journal of the Institute of Image Information and Television Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69463192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
