To address this problem, we proposed a multi-vector feature space method based on pseudo-Euclidean space and an oblique basis (MVPO). In this method, an image is represented by a solid consisting of multiple vectors; each vector corresponds to each feature. We also proposed D-distance as a distance between solids. A representative method similar to ours is Earth Mover's Distance (EMD), which is said to experimentally outperforms others including quadratic-form distance in precision. We show that EMD can be formalized as a distance in MVPO, and a reason why it outperforms quadratic-form distance. We also mention the difference between D-distance and EMD.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"90","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告情報学基礎（FI）"}],"bibliographicPageStart":"83","bibliographicIssueDates":{"bibliographicIssueDate":"2004-05-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"45(2004-FI-075)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":40249,"updated":"2025-01-22T12:31:17.977437+00:00","links":{},"created":"2025-01-18T23:07:24.475855+00:00"}
