The method is based on the dichromatic reflection model which says reflection at an object surface consists of two components, i.e. diffuse reflection and specular reflection. The components represent object color and light source color respectively and play important roles in Object Recognition and Computer Graphics. However, estimating the components separately has been difficult. The presented method based on an idea of using a cuboid to separate the components. First, it is pointed out that three surfaces of a cuboid illuminated by parallel rays give pure diffuse reflection (DR) to a camera sensing the surfaces. The second point is that normal DR radiance (NDR) corresponding to normally incident rays can be derived from radiance of the surfaces. The NDR gives the highest value of DR and light source direction. Finally, DR models at rounded edges are analytically studied and results of experiment suggest that the dichromatic reflection model is not available.","subitem_description_type":"Other"}]},"item_1_full_name_7":{"attribute_name":"著者名よみ","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"43975","nameIdentifierScheme":"WEKO"}],"names":[{"name":"モリ, カツミ"}]},{"nameIdentifiers":[{"nameIdentifier":"43976","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ワタナベ, コウジ"}]},{"nameIdentifiers":[{"nameIdentifier":"43977","nameIdentifierScheme":"WEKO"}],"names":[{"name":"カタギリ, シゲカズ"}]},{"nameIdentifiers":[{"nameIdentifier":"43978","nameIdentifierScheme":"WEKO"}],"names":[{"name":"アサノ, アツコ"}]},{"nameIdentifiers":[{"nameIdentifier":"43979","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ワタナベ, エイジ"}]}]},"item_1_full_name_8":{"attribute_name":"著者名(英)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"43980","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MORI, Katsumi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"43981","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Koji","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"43982","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KATAGIRI, Shigekazu","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"43983","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ASANO, Atsuko","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"43984","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Eiji","nameLang":"en"}]}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00217655","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Information Processing Engineering, Faculty of Engineering, Fukuyama University"},{"subitem_text_language":"en","subitem_text_value":"Department of Information Processing Engineering, Faculty of Engineering, Fukuyama University"},{"subitem_text_language":"en","subitem_text_value":"Department of Information Processing Engineering, Faculty of Engineering, Fukuyama University"},{"subitem_text_language":"en","subitem_text_value":"Fukuyama University /"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"福山大学工学部情報処理工学科"},{"subitem_text_value":"福山大学工学部情報処理工学科"},{"subitem_text_value":"福山大学工学部情報処理工学科"},{"subitem_text_value":"福山大学経済学科"},{"subitem_text_value":"甲南大学理工学部"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2004-12-01"}],"displaytype":"detail","filename":"KJ00005781587.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://fukuyama-u.repo.nii.ac.jp/record/8191/files/KJ00005781587.pdf"},"version_id":"3927dc65-c6ca-486a-9518-79da4974d13e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"拡散反射","subitem_subject_scheme":"Other"},{"subitem_subject":"物体色","subitem_subject_scheme":"Other"},{"subitem_subject":"直方体","subitem_subject_scheme":"Other"},{"subitem_subject":"2色性反射モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"光源方向","subitem_subject_scheme":"Other"},{"subitem_subject":"diffuse reflection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"object color","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cuboid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dichromatic reflection model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"light source direction","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":"物体からの拡散反射光の推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"物体からの拡散反射光の推定"},{"subitem_title":"Estimation of Diffuse Reflection at Object Surface","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["712"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-12-01"},"publish_date":"2004-12-01","publish_status":"0","recid":"8191","relation_version_is_last":true,"title":["物体からの拡散反射光の推定"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T10:27:57.530225+00:00"}
