However, appearance changes due to view direction changes cause difficulties for gait identification. We propose a method of gait identification using frequencydomain features and a view transformation model. We first extract frequency-domain features from a spatio-temporal gait silhouette volume. Next, our view transformation model is obtained with a training set of multiple persons from multiple view directions. In an identification phase, the model transforms gallery features into the same view direction as that of a probe feature. Experiments involving gait identification from 24 view directions demonstrate the effectiveness of our method.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"87","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":"78","bibliographicIssueDates":{"bibliographicIssueDate":"2007-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG1(CVIM17)","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"item_3_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"研究論文(推薦)"}]},"weko_creator_id":"1"},"id":17963,"updated":"2025-01-22T23:03:08.509846+00:00","links":{},"created":"2025-01-18T22:50:49.383826+00:00"}
