Our main contribution is to cast this task as a multi-objective optimization problem and exploits both the geometric and the appearance features for detection. Specifically, two objective functions were designed under an evolutionary optimization framework with a line pair modeled as an individual (i.e., solution). Both of the objectives follow the basic characteristics of the Braille blocks, which aim to clarify the boundaries and estimate the likelihood of the Braille block surface. Our proposed method was assessed by an originally collected and annotated dataset under real scenarios. Both quantitative and qualitative experimental results show that the proposed method can detect Braille blocks under various environments. We also provide a comprehensive comparison of the detection performance with respect to different multi-objective optimization algorithms.","subitem_description_type":"Abstract"}]},"item_16_link_13":{"attribute_name":"抄録（URL）","attribute_value_mlt":[{"subitem_link_text":"Braille Block Detection via Multi-Objective Optimization from an Egocentric Viewpoint","subitem_link_url":"https://www.mdpi.com/1424-8220/21/8/2775"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI"}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.3390/s21082775","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2021 by the authors."}]},"item_16_rights_19":{"attribute_name":"権利URI","attribute_value_mlt":[{"subitem_rights":"https://creativecommons.org/licenses/by/4.0/"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"14248220","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"Department of Engineering, University of Fukui"},{"subitem_text_value":"Department of Engineering, University of Fukui"},{"subitem_text_value":"Faculty of Engineering, Iwate University"},{"subitem_text_value":"Department of Engineering, University of Fukui"}]},"item_16_version_type_27":{"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":"TAKANO, Tsubasa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKANE, Takumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"AKASHI, Takuya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ZHANG, Chao"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-09-13"}],"displaytype":"detail","filename":"sensors-v21n82p2775.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sensors-v21n82p2775","url":"https://iwate-u.repo.nii.ac.jp/record/15789/files/sensors-v21n82p2775.pdf"},"version_id":"9917e09b-afcc-4cda-a2d4-bac6b950ff76"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Braille block detection","subitem_subject_scheme":"Other"},{"subitem_subject":"egocentric vision","subitem_subject_scheme":"Other"},{"subitem_subject":"multi-objective optimization","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":"Braille block detection via multi-objective optimization from an egocentric viewpoint","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Braille block detection via multi-objective optimization from an egocentric viewpoint"}]},"item_type_id":"16","owner":"19","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-09-13"},"publish_date":"2022-09-13","publish_status":"0","recid":"15789","relation_version_is_last":true,"title":["Braille block detection via multi-objective optimization from an egocentric viewpoint"],"weko_creator_id":"19","weko_shared_id":-1},"updated":"2023-05-15T12:50:58.186766+00:00"}
