Reliable estimation of an edge direction, edge-directed asymmetric interpolation, and the use of color samples at immediate neighbors are considered as the key guidelines for smooth and sharp image restoration. Also, special interest is directed to local areas that are rich in high spatial frequency variations. For suppression of false colors likely to occur in those areas, a hue vector representation is introduced so that the spatial correlation between different color components may be exploited in consistent with the local constant-hue principle. Smoothing is repeated in the hue vector field a few times. Experimental results have shown preferable performances in terms of PSNR, CIELAB color difference, hue angle difference, CIE chromaticity and visual appearance, in particular resulting in less false colors.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "5923", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "高橋, 善寿", "nameLang": "ja"}]}, {"nameIdentifiers": [{"nameIdentifier": "5924", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "開, 健太朗", "nameLang": "ja"}]}, {"nameIdentifiers": [{"nameIdentifier": "5925", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "菊池, 久和", "nameLang": "ja"}]}, {"nameIdentifiers": [{"nameIdentifier": "5926", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "村松, 正吾", "nameLang": "ja"}]}]}, "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/10.1093/ietfec/e91-a.4.978", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "社団法人電子情報通信学会"}, {"subitem_rights": "http://search.ieice.org/"}]}, "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": "Takahashi, Yoshihisa", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "5919", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hiraki, Kentaro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "5920", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kikuchi, Hisakazu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "5921", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Muramatsu, Shogo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "5922", "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": "E91-A(4)_978-986.pdf", "filesize": [{"value": "2.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2600000.0, "url": {"label": "E91-A(4)_978-986.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1862/files/E91-A(4)_978-986.pdf"}, "version_id": "0729f33e-cd14-4d62-8c5b-a939642ff28c"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "image processing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "color demosaicing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "interpolation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "CFA", "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": "Color Demosaicing Using Asymmetric Directional Interpolation and Hue Vector Smoothing", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Color Demosaicing Using Asymmetric Directional Interpolation and Hue Vector Smoothing", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/9913", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-12-28"}, "publish_date": "2009-12-28", "publish_status": "0", "recid": "1862", "relation": {}, "relation_version_is_last": true, "title": ["Color Demosaicing Using Asymmetric Directional Interpolation and Hue Vector Smoothing"], "weko_shared_id": -1}
