In this paper, we propose a fast motion vector detection algorithm using steepest descent method which is one of gradient methods. Proposed method is capable of avoiding the local minima problem by employing adaptive initial vector setting and hierarchical algorithm, arid obtaining improvement of predictive performance and computational complexity. From simulation, we compare predictive performance and computational complexity with other methods, and show effectiveness of the proposed method. And also, we show performance of proposed method in the case of applying it to interlaced images.","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/110002913635/","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":"AN10438399","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0919-6072","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-1.pdf","filesize":[{"value":"558.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-IMAMURA-K-1.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/9901/files/TE-PR-IMAMURA-K-1.pdf"},"version_id":"acf57bd1-5719-483e-907a-88c111282703"}]},"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の高速化とインターレース画像への適用","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の高速化とインターレース画像への適用"},{"subitem_title":"A Fast Motion Vector Detection Using Steepest Descent Method and Applying it to Interlaced Images","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":"9901","relation_version_is_last":true,"title":["最急降下法を用いた動きベクトル検出の高速化とインターレース画像への適用"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:47:05.732891+00:00"}
