This plotter is an image processing system designed for aerial photogrammetry for map produciton. Since data volume is quite large, efficient data compression techniques are important. In aerial photogrammetry different pixel sizes are required in orientation of images and plotting object contours. In this aspect pyramidal image compression, including the GBTC (Generalized Block Truncation Coding) algorithm, looks most appropriate. But the GBTC algorthm does not preserve edges of images, and loses significant information when plotting object contours. The authors propose a method to store positions of edges instead of quantization levels in GBTC. The experiments illustrates the quality comparison of decompressed images with the GBTC and the authors' method. The result shows the latter is superior both in precision of idenfifying point pairs in stereo images and the compression rate.","subitem_description_type":"Other"}]},"item_1_full_name_7":{"attribute_name":"著者名よみ","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"42746","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ハットリ, ススム"}]},{"nameIdentifiers":[{"nameIdentifier":"42747","nameIdentifierScheme":"WEKO"}],"names":[{"name":"セキ, アキヨシ"}]},{"nameIdentifiers":[{"nameIdentifier":"42748","nameIdentifierScheme":"WEKO"}],"names":[{"name":"イノウエ, ノリヒト"}]}]},"item_1_full_name_8":{"attribute_name":"著者名(英)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"42749","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HATTORI, Susumu","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"42750","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SEKI, Akiyoshi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"42751","nameIdentifierScheme":"WEKO"}],"names":[{"name":"INOUE, Norihito","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_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":"福山大学工学部情報処理工学科"},{"subitem_text_value":"福山大学工学部工学研究科情報処理工学専攻"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1995-11-01"}],"displaytype":"detail","filename":"KJ00005781340.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://fukuyama-u.repo.nii.ac.jp/record/7954/files/KJ00005781340.pdf"},"version_id":"c4061c4f-7de2-494b-b7d8-49287e82dbf3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Image Compression","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Edges","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LoG filter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Precision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"GBTC Algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Digital Image-Based Plotter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Digital Photogrammetry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Measurement","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":"エッジを保った画像圧縮法 : GBTC法との比較(B.一般論文,開学20周年記念特集号)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"エッジを保った画像圧縮法 : GBTC法との比較(B.一般論文,開学20周年記念特集号)"},{"subitem_title":"Edge Preserving Image Compression : Comparison with the GBTC Method(B.Article,Special Edition for the 20th Anniversary of the University)","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["699"],"pubdate":{"attribute_name":"公開日","attribute_value":"1995-11-01"},"publish_date":"1995-11-01","publish_status":"0","recid":"7954","relation_version_is_last":true,"title":["エッジを保った画像圧縮法 : GBTC法との比較(B.一般論文,開学20周年記念特集号)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T10:33:22.006252+00:00"}
