Here, one is an original image and the other is a point spread function (PSF) which causes degradation of original images. Blind deconvolution (BD) is the problem to estimate an original image and a PSF from only a degraded image. If we have no restriction condition to signals, we can not determine a pair of two signals. Because this problem sometimes has many solutions and, in the worst case, has infinite solutions. Nevertheless, almost everyone does not discuss this indeterminate property. In this paper, we show that BD has only finite solutions if an original image and a PSF are nonzero over a restricted domain, in other words, an observed image has finite support. Then we propose an algorithm to find all finite solutions under this boundary condition. The key of the proof is to use z transformation and factorization of polynomials. Moreover, we give a sufficient condition in which BD has only one solution. Finally we confirm that we can extract all sets of an original image and a PSF from a degraded image by using our algorithm in numerical examples.","subitem_description_type":"Other"}]},"item_1_full_name_7":{"attribute_name":"著者名よみ","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"43755","nameIdentifierScheme":"WEKO"}],"names":[{"name":"オゼキ, タカシ"}]},{"nameIdentifiers":[{"nameIdentifier":"43756","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ワタナベ, エイジ"}]},{"nameIdentifiers":[{"nameIdentifier":"43757","nameIdentifierScheme":"WEKO"}],"names":[{"name":"イシカワ, ヒロシ"}]},{"nameIdentifiers":[{"nameIdentifier":"43758","nameIdentifierScheme":"WEKO"}],"names":[{"name":"コバヤシ, フジオ"}]}]},"item_1_full_name_8":{"attribute_name":"著者名(英)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"43759","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OZEKI, Takashi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"43760","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Eiji","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"43761","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ISHIKAWA, Hiroshi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"43762","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOBAYASHI, Fujio","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"}]},"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":"甲南大学理工学部情報システム工学科"},{"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"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2003-12-01"}],"displaytype":"detail","filename":"KJ00005781547.pdf","filesize":[{"value":"509.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://fukuyama-u.repo.nii.ac.jp/record/8151/files/KJ00005781547.pdf"},"version_id":"ff2f431f-692d-4a9e-8cb2-761bb7aad39a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ブラインドデコンボルーション","subitem_subject_scheme":"Other"},{"subitem_subject":"画像復元","subitem_subject_scheme":"Other"},{"subitem_subject":"デジタル信号処理","subitem_subject_scheme":"Other"},{"subitem_subject":"z変換","subitem_subject_scheme":"Other"},{"subitem_subject":"多項式の因数分解","subitem_subject_scheme":"Other"},{"subitem_subject":"Blind Deconvolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Image Restoration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Digital Signal Processing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Z Transformation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Factorization of Polynomials","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":"多項式の因数分解を利用した劣化画像の復元法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多項式の因数分解を利用した劣化画像の復元法"},{"subitem_title":"A Restoration Method of Degraded Images using Factorization of Polynomials","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["711"],"pubdate":{"attribute_name":"公開日","attribute_value":"2003-12-01"},"publish_date":"2003-12-01","publish_status":"0","recid":"8151","relation_version_is_last":true,"title":["多項式の因数分解を利用した劣化画像の復元法"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T10:29:31.506219+00:00"}
