In this article, a method to investigate historical artifacts based on imagery techniques is discussed and examined as a basic study. In the method, spectral selectivity is focused on to extract information from taken images of the artifacts. The selectivity of wavelength in spectra is realized by changing light sources and filters used in the imagery. The proposed method is aimed to be one of investigation procedures in a total artifact investigation system including scientific or chemical investigation methods. The proposed method is applied to a matchlock and a Nishikie prepared for the research purposes. As a result of this research, information that is invisible for the human visual system is extracted by the proposed method, however it is difficult to conclude that the extracted information could provide effectiveness for the artifact investigation because the proposed method is limited to the basic investigations. More experimental results by the proposed method as well as improvements of the analyzing technique is required to extract the information from taken images as future work.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"歴史資料に対する自然科学的調査法の開発と適用に関する研究","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Research on the Development and Application of Natural Science Methods of Analyzing Historical Materials","subitem_heading_language":"en"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15024/00000221","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立歴史民俗博物館","subitem_publisher_language":"ja"}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"第177集 収録論文 タイトルリスト"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.rekihaku.ac.jp/outline/publication/ronbun/ronbun8/index.html#no177","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00377607","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-7400","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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":"宮田,  公佳","creatorNameLang":"ja"},{"creatorName":"ミヤタ, キミヨシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyata, Kimiyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-04-01"}],"displaytype":"detail","filename":"kenkyuhokoku_177_01.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_177_01","url":"https://rekihaku.repo.nii.ac.jp/record/237/files/kenkyuhokoku_177_01.pdf"},"version_id":"a982f4c4-432d-4579-b587-09e1b898699a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"分光画像","subitem_subject_scheme":"Other"},{"subitem_subject":"画像技術","subitem_subject_scheme":"Other"},{"subitem_subject":"フィルタリング","subitem_subject_scheme":"Other"},{"subitem_subject":"画像解析","subitem_subject_scheme":"Other"},{"subitem_subject":"spectral imaging","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"imaging technology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"filtering","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"image analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"波長選択的像形成による歴史資料の画像解析に関する基礎検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"波長選択的像形成による歴史資料の画像解析に関する基礎検討","subitem_title_language":"ja"},{"subitem_title":"Basic Study on Imagery for Historical Artifacts Based on Spectral Selective Imaging Systems","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["22"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-01-04"},"publish_date":"2016-01-04","publish_status":"0","recid":"237","relation_version_is_last":true,"title":["波長選択的像形成による歴史資料の画像解析に関する基礎検討"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-14T06:02:54.800557+00:00"}
