The method employs bits truncation of the gray level from 8 bits to much less bits in the searching algorithm. Compared with conventional fast block matching algorithms, this method drastically improves speed for motion estimation on reduced gray-level images and preserves reasonable performance and algorithm reliability. Bits truncation concept is well combined with hierarchical pyramid algorithm in order to truncate adaptively according to image characteristics. The computation complexity is much less than that of pyramid algorithm and 3-Step motion estimation algorithm because of bit-truncated search and low overhead adaptation. Nevertheless, the PSNR property is also comparable with these two algorithms for various video sequences.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"copyright(c)1997 \nIEICE許諾番号：08RB0009","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人電子情報通信学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168508","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"ITO, Kazuhito"},{"subitem_text_value":"JIANG, Li"},{"subitem_text_value":"KUNIEDA, Hiroaki"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1003002"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学情報機構情報メディア基盤センター学術情報処理研究開発部門"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"The Information Processing Center, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"1997-8"}]},"item_119_version_type_28":{"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":"伊藤, 和人"},{"creatorName":"イトウ, カズヒト","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"18709","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"TfwxTeoe","nameIdentifierScheme":"研究者総覧","nameIdentifierURI":"http://s-read.saitama-u.ac.jp/researchers/pages/researcher/TfwxTeoe"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1003002.pdf","filesize":[{"value":"669.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1003002.pdf","url":"https://sucra.repo.nii.ac.jp/record/14345/files/A1003002.pdf"},"version_id":"0ca3c560-de4f-47e0-bedb-6b9bea040630"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bits truncation","subitem_subject_scheme":"Other"},{"subitem_subject":"adaptive","subitem_subject_scheme":"Other"},{"subitem_subject":"pyramid","subitem_subject_scheme":"Other"},{"subitem_subject":"motion estimation","subitem_subject_scheme":"Other"},{"subitem_subject":"MPEG2","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Bits Truncation Adaptive Pyramid Algorithm for Motion Estimation of MPEG2 (Special Section on Digital Signal Processing)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Bits Truncation Adaptive Pyramid Algorithm for Motion Estimation of MPEG2 (Special Section on Digital Signal Processing)"}]},"item_type_id":"119","owner":"3","path":["242"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-30"},"publish_date":"2008-01-30","publish_status":"0","recid":"14345","relation_version_is_last":true,"title":["Bits Truncation Adaptive Pyramid Algorithm for Motion Estimation of MPEG2 (Special Section on Digital Signal Processing)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:01:55.224253+00:00"}
