Proposed method is capable of avoiding the local minima problem by employing adaptive initial vector setting and hierarchical algorithm, and obtaining improvement of prediction performance. From simulation results, we compare prediction performance and computational complexity with other methods, and show effectiveness of the proposed method.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域電子情報学系","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/10013765544/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"利用は著作権の範囲内に限られる"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00116647","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-5806","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"今村, 幸祐"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"中西, 靖人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋本, 秀雄"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-IMAMURA-K-2528.pdf","filesize":[{"value":"111.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-IMAMURA-K-2528.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/7962/files/TE-PR-IMAMURA-K-2528.pdf"},"version_id":"b5b40988-c58e-46ca-b9bb-29f0d09c696c"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"最急降下法を用いた動きベクトル検出における局所解の回避とその効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"最急降下法を用いた動きベクトル検出における局所解の回避とその効果"},{"subitem_title":"Improvement of Local Minima Problem and Its Effectiveness for Motion Vector Detection Using Steepest Descent Method","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"7962","relation_version_is_last":true,"title":["最急降下法を用いた動きベクトル検出における局所解の回避とその効果"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T02:16:40.924045+00:00"}
