The major achievements were development of a dictionary design technique for sparse coding corresponded to Poisson noise and a fast atom selection method using initial inner product. These proposed method provided good noise reduction performance. On the other hand, we designed hardware of a fast processing algorithm using Cholesky decomposition, and evaluated the performance.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:26420350, 研究期間(年度):2001-2015","subitem_description_type":"Other"},{"subitem_description":"出典：「スパースコーディングに基づく医療画像処理技術の開発とハードウェア実装」研究成果報告書　課題番号26420350\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26420350/26420350seika/ ）を加工して作成","subitem_description_type":"Other"}]},"item_9_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通信学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052020","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=00324096"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=00324096","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26420350/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26420350/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26420350/26420350seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26420350/26420350seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-08-24"}],"displaytype":"detail","filename":"TE-PR-IMAMURA-K-kaken 2017-4p.pdf","filesize":[{"value":"455.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-IMAMURA-K-kaken 2017-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45683/files/TE-PR-IMAMURA-K-kaken 2017-4p.pdf"},"version_id":"31c48d79-f785-46a3-b637-04785aa5f6ec"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"スパースコーディングに基づく医療画像処理技術の開発とハードウェア実装","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スパースコーディングに基づく医療画像処理技術の開発とハードウェア実装"},{"subitem_title":"Development of Medical Image Processing Technology Based on Sparse Coding and Hardware Implementation","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2817"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-08-24"},"publish_date":"2018-08-24","publish_status":"0","recid":"45683","relation_version_is_last":true,"title":["スパースコーディングに基づく医療画像処理技術の開発とハードウェア実装"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T11:22:18.649017+00:00"}
