The filter coefficients are optimized by the minimization of the squared error norm between the Fourier power spectra of the resulting halftone and the blue noise pattern. During the process of optimization, the binary pattern power spectrum matching algorithm is applied with the aid of a new blue noise model. The number of the optimum filters is equal to that of different tones. The visual fidelity of the bilevel halftones generated by the error diffusion filters is valuated in terms of a weighted signal-to-noise ratio, Fourier power spectra, and others. Experimental results have demonstrated the proposed filter set generates satisfactory bilevel halftones of grayscale images.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "電子情報通信学会", "subitem_publisher_language": "ja"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1587/transfun.e93.a.1465", "subitem_relation_type_select": "DOI"}}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.ieice.org/jpn/trans_online/", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright©2010 IEICE"}]}, "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": "AA10826239", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0916-8508", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hwang, Junghyeun", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "5876", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kikuchi, Hisakazu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "5877", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Muramatsu, Shogo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "5878", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shin, Jaeho", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "5879", "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": "E93-A_8_1465-1475.pdf", "filesize": [{"value": "2.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2100000.0, "url": {"label": "E93-A_8_1465-1475.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1856/files/E93-A_8_1465-1475.pdf"}, "version_id": "7201250d-fcb1-40fc-8f03-1344c8cab7e2"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "digital halftoning", "subitem_subject_scheme": "Other"}, {"subitem_subject": "error diffusion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "blue noise", "subitem_subject_scheme": "Other"}, {"subitem_subject": "power spectrum", "subitem_subject_scheme": "Other"}, {"subitem_subject": "binary pattern power spectrum matching", "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": "An Optimum Design of Error Diffusion Filters Using the Blue Noise in All Graylevels", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "An Optimum Design of Error Diffusion Filters Using the Blue Noise in All Graylevels", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/18502", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2012-06-08"}, "publish_date": "2012-06-08", "publish_status": "0", "recid": "1856", "relation": {}, "relation_version_is_last": true, "title": ["An Optimum Design of Error Diffusion Filters Using the Blue Noise in All Graylevels"], "weko_shared_id": -1}
