In this paper, we propose a new unsupervised design method of WMFs. To recover images from the noise, any filters must preserve original values of non-corruped pixels and simultaneously well estimate the original values of corrupted pixels; however, the preservation quality and the restoration quality often have a trade-off relation. We formulate the design of WMF as a multi-objective optimization problem that treats the preservation performance and the restoration performance as conflict functions. Through the experiments, we show our method obtains a wide variety of filters that have the high preservation performance or the high restoration performance at one search process.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告数理モデル化と問題解決（MPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-02-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2013-MPS-92"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:40:00.494201+00:00","id":90425,"links":{}}
