Spatial scalability is implemented by using a multiresolution representation produced by a wavelet expansion. Quality scalability is implemented by using a multiprecision representation produced by multistage zero run-length coding after nonlinear quantization. The data rate is controlled by threshold values and/or spatial resolution in the wavelet expansion. The coding method owes its fine scalability and higher compression to multiresolution decomposition, nonlinear quantization, multistage zero run-length coding and arithmetic coding. In addition to the simplicity in coding, edges and outlines are well preserved without blocking noise at low bit rates. A few examples are also given.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "38967", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Abe, Yoshito"}]}, {"nameIdentifiers": [{"nameIdentifier": "38968", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kikuchi, Hisakazu"}]}, {"nameIdentifiers": [{"nameIdentifier": "38969", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sasaki, Shigenobu"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "映像情報メディア学会"}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "社団法人映像情報メディア学会"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN10588970", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13426907", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "阿部, 淑人"}], "nameIdentifiers": [{"nameIdentifier": "38964", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "菊池, 久和"}], "nameIdentifiers": [{"nameIdentifier": "38965", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "佐々木, 重信"}], "nameIdentifiers": [{"nameIdentifier": "38966", "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": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "51_11_1889-1898.pdf", "filesize": [{"value": "1.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1400000.0, "url": {"label": "51_11_1889-1898.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2771/files/51_11_1889-1898.pdf"}, "version_id": "004d75aa-118b-4516-b367-c733ccee8083"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "ウェーブレット", "subitem_subject_scheme": "Other"}, {"subitem_subject": "多重解像度表現", "subitem_subject_scheme": "Other"}, {"subitem_subject": "閾値付き多段ラン長符号化", "subitem_subject_scheme": "Other"}, {"subitem_subject": "多重精度表現", "subitem_subject_scheme": "Other"}, {"subitem_subject": "スケーラビリティ", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "ウェーブレット画像符号化による品質・空間スケーラビリティ", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "ウェーブレット画像符号化による品質・空間スケーラビリティ"}, {"subitem_title": "ウェーブレット画像符号化による品質・空間スケーラビリティ", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/17991", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-05-16"}, "publish_date": "2012-05-16", "publish_status": "0", "recid": "2771", "relation": {}, "relation_version_is_last": true, "title": ["ウェーブレット画像符号化による品質・空間スケーラビリティ"], "weko_shared_id": null}
