Lossy image compression method such as JPEG is often used for reference images. The purpose of this study is to develop a new image compression method to apply different compression ratio to the inside of ROIs according to normal JPEG scheme. ROIs can be often defined as more significant regions than others by radiologists. By using our method，two quantization matrices were used in the phase of encoding. We studied the quantization matrix for outside of ROI to minimize the degradation of image quality. The image size was 7.3% smaller than the normal JPEG images. It is easy to introduce our method into PACS，since any additional software was not required to decode image data compressed by the proposed method.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_full_name_3":{"attribute_name":"著者（英）","attribute_value_mlt":[{"names":[{"name":"Okura, Yasuhiko","nameLang":"en"}]},{"names":[{"name":"Yamamoto, Megumi","nameLang":"en"}]}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.60172/00000313","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"広島国際大学大学院総合人間科学研究科医療工学専攻"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12217173","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1881-9265","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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":"大倉, 保彦","creatorNameLang":"ja"},{"creatorName":"オオクラ, ヤスヒコ","creatorNameLang":"ja-Kana"}]},{"creatorNames":[{"creatorName":"山本, めぐみ","creatorNameLang":"ja"},{"creatorName":"ヤマモト, メグミ","creatorNameLang":"ja-Kana"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-03-11"}],"displaytype":"detail","filename":"jme05_031.pdf","filesize":[{"value":"426.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jme05_031.pdf","url":"https://hirokoku-u.repo.nii.ac.jp/record/319/files/jme05_031.pdf"},"version_id":"4c102307-bb8f-4188-8025-bef3d5f16e6d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"image compression","subitem_subject_scheme":"Other"},{"subitem_subject":"medical image","subitem_subject_scheme":"Other"},{"subitem_subject":"digital image","subitem_subject_scheme":"Other"},{"subitem_subject":"image storage","subitem_subject_scheme":"Other"},{"subitem_subject":"electronic medical record","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":"関心領域に異なる圧縮比を適用できるJPEG圧縮符号化法に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"関心領域に異なる圧縮比を適用できるJPEG圧縮符号化法に関する研究","subitem_title_language":"ja"},{"subitem_title":"Development of an image compression method to realize different compression ratio to the inside of ROI according to the JPEG scheme","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"4","path":["67"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-11"},"publish_date":"2023-03-11","publish_status":"0","recid":"319","relation_version_is_last":true,"title":["関心領域に異なる圧縮比を適用できるJPEG圧縮符号化法に関する研究"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2024-07-22T07:28:36.606714+00:00"}
