(2) We proposed the usage of Renyi‘s alpha-entropy as a measure of width of marginal distribution and obtained very intuitive new and simple ICA methods. (3) We proposed an adaptive method for smoothing the periodogram for positive time-frequency representation. For impulse train time-frequency analysis, we proposed an inverse domain demodulation method of IPFM and an objective evaluation method for demodulators. Further, we proposed distance estimation method exploiting time-frequency feature of reflected signal from a moving object.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究 (C);  研究期間：2007～2010;   課題番号：19500245;   研究分野：情報工学;   科研費の分科・細目：情報学・統計科学","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/30075329"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/50278735"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/90188920"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/60063806"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"連携研究者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"KIKKAWA, SHO"},{"subitem_text_language":"en","subitem_text_value":"YOSHIDA, HISASHI"},{"subitem_text_language":"en","subitem_text_value":"NAKASAKO, NOBORU"},{"subitem_text_language":"en","subitem_text_value":"HASHIMOTO, SHUJI"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学生物理工学部; 研究員"},{"subitem_text_value":"近畿大学生物理工学部; 准教授"},{"subitem_text_value":"近畿大学生物理工学部; 教授"},{"subitem_text_value":"早稲田大学理工学術院; 教授"}]},"item_8_version_type_12":{"attribute_name":"版","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":"吉川,  昭"},{"creatorName":"キッカワ, ショウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3515","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60063806","nameIdentifierScheme":"研究者番号","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"吉田,  久"},{"creatorName":"ヨシダ, ヒサシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3516","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中迫,  昇"},{"creatorName":"ナカサコ, ノボル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3517","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"橋本,  周司"},{"creatorName":"ハシモト, シュウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3518","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_19500245seika.pdf","filesize":[{"value":"432.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_19500245seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3156/files/KAKEN_19500245seika.pdf"},"version_id":"a6e72692-3fca-42ff-88a9-70641b126b2b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"α次エントロピー","subitem_subject_scheme":"Other"},{"subitem_subject":"画像閾値決定","subitem_subject_scheme":"Other"},{"subitem_subject":"信号解析","subitem_subject_scheme":"Other"},{"subitem_subject":"独立成分分析","subitem_subject_scheme":"Other"},{"subitem_subject":"生体信号解析","subitem_subject_scheme":"Other"},{"subitem_subject":"相互情報量","subitem_subject_scheme":"Other"},{"subitem_subject":"IPFM","subitem_subject_scheme":"Other"},{"subitem_subject":"移動体間距離推定","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"α次エントロピーなど拡張形エントロピーによる近代的信号・画像解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"α次エントロピーなど拡張形エントロピーによる近代的信号・画像解析"}]},"item_type_id":"8","owner":"3","path":["2693","2694"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-07-08"},"publish_date":"2011-07-08","publish_status":"0","recid":"3156","relation_version_is_last":true,"title":["α次エントロピーなど拡張形エントロピーによる近代的信号・画像解析"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:44:51.452526+00:00"}
