The RLS Wiener estimators use the auto-covariance function of the signal，the system matrix φ for the n by 1 zero-mean signal vector s(i，j)，which is obtained by subtracting the mean of the image signal x(i，j) from the signal values of the image，the variance of s(i，j) and the variance of the white observation noise. Here，for the two-dimensional zero-mean values s(i，j)，i= 1，2，・・・，M，j=1，2，・・・，N，the n by 1 vector consisting of the components s(i，j)， i=1，2，・・・，n，are estimated along the horizontal direction for j=1，2，・・・，N.Next，the n by 1 vector consisting of s(i，j)，i=n+1，n+2，・・・，2n，are estimated，recursively from the left to the right column，similarly. This procedure is continued，at last，to the last columnj=N for the bottom n by 1 vector of s(i，j). Finally，the estimates of the image are obtained by adding the mean to the estimates of s(i，j).","subitem_description_type":"Other"}]},"item_7_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"中森, 誠一"}]}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03896692","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00408518","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"410","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_7_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_7_version_type_14":{"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":"Nakamori, Seiichi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"4_Nakamori.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"4_Nakamori.pdf","url":"https://ir.kagoshima-u.ac.jp/record/10362/files/4_Nakamori.pdf"},"version_id":"c8ae1460-eeaa-4ab4-81bd-b16afe12733f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Wiener-Hopf equation","subitem_subject_scheme":"Other"},{"subitem_subject":"linear discrete-time systems","subitem_subject_scheme":"Other"},{"subitem_subject":"recursive Wiener filter","subitem_subject_scheme":"Other"},{"subitem_subject":"auto-covariance function","subitem_subject_scheme":"Other"},{"subitem_subject":"image restoration","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Image Restoration Technique by RLS Wiener Fixed-Point Smoother and Filter","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Image Restoration Technique by RLS Wiener Fixed-Point Smoother and Filter"}]},"item_type_id":"7","owner":"3","path":["42","5040"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-05-18"},"publish_date":"2010-05-18","publish_status":"0","recid":"10362","relation_version_is_last":true,"title":["Image Restoration Technique by RLS Wiener Fixed-Point Smoother and Filter"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T02:10:04.131425+00:00"}
