Measures of the above algorithm performance are composed of three entities : (a)amount of data reduction. (b) quantitative or qualitative assessment of the degradation of the image data, and (c) compression/expansion processing speed. In this study, a set of RGB components of color images is transformed into a set of YIQ data. Hadamard transform coding of the Y component of color images is performed. The features of a boundary threshold method in contrast to other some methods are discussed together with the quantitative measure such as the degree of similarity and the ratio of file compression. Reconstructed images after executing compression and expansion are presented in order to demonstrate a visual assessment of the degradation of the images.","subitem_description_type":"Other"}]},"item_2_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"7","subitem_description_type":"Other"}]},"item_2_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00001511969","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_2_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00159741","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03876055","subitem_source_identifier_type":"ISSN"}]},"item_2_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京工芸大学工学部電子工学科"},{"subitem_text_value":"ソニー株式会社"}]},"item_2_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"カラーガゾウ ノ アダマールヘンカンンフゴウカ ト ガゾウアッシュク"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"飯塚, 昌之"},{"creatorName":"イイヅカ, マサユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"490","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"駒井, 義弘"},{"creatorName":"コマイ, ヨシヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"491","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"IIZUKA, Masayuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"492","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KOMAI, Yoshihiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"493","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":"2017-04-21"}],"displaytype":"detail","filename":"KJ00001511969.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00001511969.pdf","url":"https://kougei.repo.nii.ac.jp/record/194/files/KJ00001511969.pdf"},"version_id":"a957a690-55dc-4066-8645-bb0306808a8c"}]},"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":"カラー画像のアダマール変換符号化と画像圧縮","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"カラー画像のアダマール変換符号化と画像圧縮"},{"subitem_title":"Hadamard Transform Coding of Color Images and Image Compression","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["45"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-21"},"publish_date":"2017-04-21","publish_status":"0","recid":"194","relation_version_is_last":true,"title":["カラー画像のアダマール変換符号化と画像圧縮"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T14:23:09.421448+00:00"}
