The extraction algorithm has two processes, 1) an extraction of the book images from the bookshelf image, 2) an extraction of character regions from the book images. In the first stage, the bookshelf image is divided into several sectors based on the direction of density gradient of the image pixels. Then, by applying the Hough translation, the straight lines composing the edge lines of the book images can be detected. In the second process, we use the peripheral distribution of the book image to detect the width and height of each character. Using 23 bookshelf images containing 124 books with 1227 characters, we obtained an extraction rate of book images of 93.5 (%) and an extraction rate of character regions of 89.9 (%).","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00033244","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Graduate School of Engineering, Okayama University of Science"},{"subitem_text_language":"en","subitem_text_value":"Department of Information & Computer Engineering, Okayama University of Science"},{"subitem_text_language":"en","subitem_text_value":"Department of Information & Computer Engineering, Okayama University of Science"},{"subitem_text_language":"en","subitem_text_value":"Department of Electronic Engineering, Okayama University of Science"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"岡山理科大学大学院工学研究科修士課程電子工学専攻"},{"subitem_text_language":"ja","subitem_text_value":"岡山理科大学工学部情報工学科"},{"subitem_text_language":"ja","subitem_text_value":"岡山理科大学工学部情報工学科"},{"subitem_text_language":"ja","subitem_text_value":"岡山理科大学工学部電子工学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1997-03-31"}],"displaytype":"detail","filename":"KJ00000063705.pdf","filesize":[{"value":"779.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://ous.repo.nii.ac.jp/record/1196/files/KJ00000063705.pdf"},"version_id":"008b2f50-a7d9-469e-81f8-26b76fe19d33"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"書棚画像からの書籍の背文字領域の抽出について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"書棚画像からの書籍の背文字領域の抽出について","subitem_title_language":"ja"},{"subitem_title":"A Study of Extraction of Character Regions from Bookshelf Images","subitem_title_language":"en"},{"subitem_title":"ショダナ ガゾウ カラノ ショセキ ノ セモジ リョウイキ ノ チュウシュツニツイテ","subitem_title_language":"ja-Kana"}]},"item_type_id":"1","owner":"14","path":["330"],"pubdate":{"attribute_name":"PubDate","attribute_value":"1997-03-31"},"publish_date":"1997-03-31","publish_status":"0","recid":"1196","relation_version_is_last":true,"title":["書棚画像からの書籍の背文字領域の抽出について"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-09-28T00:55:55.998003+00:00"}
