When we consider an application such as image comparison processing in which image data, compressed and stored beforehand, must be decoded and compared with image data from some input device (e.g., raster scan-type camera), the work of decoding data must be able to produce outputs one after another in sequence within a prescribed time frame. However, the existing methods of data compression for bi-level images do not satisfactorily fulfill the above listed requirements for real-time decoding processes. For this reason, we propose a compression code called the \"Binary Place Compression (BPC) Code\", which possesses the real-time nature required for such bi-level image processing as described above. This BPC code has the following features: (1) sequential real-time processing capability, (2) loss-less coding/decoding, (3) simplicity of coding/decoding procedure resulting in easy hardware implementation, etc. Also in this work, we prototyped a decoder for BPC with a gate-array and produced an image processing unit. We verified the applicability of our proposed code by evaluating the prototype in a practical application for constructing a quality evaluation system for printed circuit boards. Finally, we also verified that the compression rate of our code exceeds that of other binary compression codes used in the past.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等専門学校"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-1909","subitem_source_identifier_type":"ISSN"}]},"item_2_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":"和崎, 克己"}],"nameIdentifiers":[{"nameIdentifier":"768","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"不破, 泰"}],"nameIdentifiers":[{"nameIdentifier":"769","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"江口, 正義"}],"nameIdentifiers":[{"nameIdentifier":"770","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村, 八束"}],"nameIdentifiers":[{"nameIdentifier":"771","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":"2013-02-19"}],"displaytype":"detail","filename":"nagano_nct-31-08.pdf","filesize":[{"value":"682.3 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-31-08.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/343/files/nagano_nct-31-08.pdf"},"version_id":"269ba369-3ce9-4102-b697-321cc83b104c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"2値画像","subitem_subject_scheme":"Other"},{"subitem_subject":"画像符号化","subitem_subject_scheme":"Other"},{"subitem_subject":"ロスレス","subitem_subject_scheme":"Other"},{"subitem_subject":"データ圧縮","subitem_subject_scheme":"Other"},{"subitem_subject":"リアルタイム処理","subitem_subject_scheme":"Other"},{"subitem_subject":"ゲートアレイ","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":"逐次リアルタイム復号処理が可能な2値画像圧縮法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"逐次リアルタイム復号処理が可能な2値画像圧縮法"}]},"item_type_id":"2","owner":"17","path":["34"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-19"},"publish_date":"2013-02-19","publish_status":"0","recid":"343","relation_version_is_last":true,"title":["逐次リアルタイム復号処理が可能な2値画像圧縮法"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T16:10:25.757640+00:00"}
