Video coding methods have been based on hybrid coding which employs motion compensation and discrete cosine transform. But, another high efficiency video coding method in low bit rate using matching pursuits, that is one of waveform coding techniques, is suggested recently. The matching pursuits algorithm represents a signal approximately using a dictionary. Matching pursuits generally use separable dictionary composed of one dimensional basis functions. But, it is difficult for separable dictionary to code images including slant patterns efficiently. In this paper, we design the dictionary for slant patterns by a simple geometric transform. And we propose a dictionary design algorithm by employing learning technique like codebook design of vector quantization.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域電子情報学系","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002950523/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"利用は著作権の範囲内に限られる"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10438399","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0919-6072","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"加古, 真哉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"今村, 幸祐"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"橋本, 秀雄"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-IMAMURA-K-89.pdf","filesize":[{"value":"787.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-IMAMURA-K-89.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/9929/files/TE-PR-IMAMURA-K-89.pdf"},"version_id":"5952fd28-4bc5-478a-9729-73a9514a56bf"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Matching Pursuitsにおける斜めパターン対応辞書と学習による設計(画像符号化・通信・ストリーム技術,及び一般)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Matching Pursuitsにおける斜めパターン対応辞書と学習による設計(画像符号化・通信・ストリーム技術,及び一般)"},{"subitem_title":"Matching Pursuits using Slant Patterns and Dictionary Design by Learning","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"9929","relation_version_is_last":true,"title":["Matching Pursuitsにおける斜めパターン対応辞書と学習による設計(画像符号化・通信・ストリーム技術,及び一般)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:46:37.880443+00:00"}
