Distributed video coding (DVC) is a new video coding method having low encoding complexity. Conventional DVCs, however, generally suffer from lower peak signal-to-noise ratio (PSNR) than MPEG family of standards. To improve PSNR of DVC, this paper presents a new decoding algorithm based on nonbinary sum-product algorithm. Evaluation shows that PSNR of the proposed decoding algorithm is comparable to that of MPEG-1 coding.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0049500084","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-06-006","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構 総合技術研究本部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Aerospace Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"金子, 晴彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kaneko, Haruhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"49500084.pdf","filesize":[{"value":"627.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"49500084.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6068/files/49500084.pdf"},"version_id":"2be34c44-0c64-49d0-96ec-333b6835ad9b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ビデオ圧縮","subitem_subject_scheme":"Other"},{"subitem_subject":"衛星通信","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙機電子機器","subitem_subject_scheme":"Other"},{"subitem_subject":"データハンドリングシステム","subitem_subject_scheme":"Other"},{"subitem_subject":"分散ビデオ符号化","subitem_subject_scheme":"Other"},{"subitem_subject":"アルゴリズム","subitem_subject_scheme":"Other"},{"subitem_subject":"計算機プログラム","subitem_subject_scheme":"Other"},{"subitem_subject":"video compression","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"satellite communication","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spacecraft electronic equipment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"data handling system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"distributed video coding","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computer program","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"低計算量動画像圧縮方式の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低計算量動画像圧縮方式の研究"}]},"item_type_id":"3","owner":"1","path":["1028","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6068","relation_version_is_last":true,"title":["低計算量動画像圧縮方式の研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:02:43.740552+00:00"}
