(既知単語) のデータ数増加に対しては，既存モデルを活用できるかもしれないが，学習外単語 (未知単語)に対しては，既知単語のいずれかに認識しようとする既存モデルの活用は困難である．この問題に対応するためには，既知単語か未知単語かで処理が異なるため，まずラベルの付いていない手話単語動画の手話動作が既知単語か未知単語かを区別する必要がある．本研究では，未知単語動画の有効活用のために，ラベルの付いていない手話単語動画が未知単語かを判定する手法を提案する．具体的には，3DCNN ベースの手法により手話動作を時空間特徴量列で表し，特徴量同士の類似度を求めることで，未知単語かを判定する．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","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":"2022-05-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"14","bibliographicVolumeNumber":"2022-CVIM-230"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":217827,"updated":"2025-01-19T15:21:55.332384+00:00","links":{},"created":"2025-01-19T01:18:15.359737+00:00"}
