There is therefore a need to mechanize and automate aspects related to work usually performed by humans in the fishery industry. In this research, a system for identifying fish species has been developed. The system employs neural networks which learn to differentiate between different fish species using reference points. Reference points are characteristic points that are extracted from images of the body surface of the fish using a method that employs the truss protocol. The ratios of specific truss lengths between reference points relative to total body length are used to compile the dataset used for network inputs. For fish with bodies that have been contorted, only data from the vicinity of the fish head are used for network learning. Given that body color is an important characteristic for species identification, an effective method for capturing color data was investigated and the effectiveness of the proposed method and optimal number of color parameters was determined.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産大学校","subitem_publisher_language":"ja"},{"subitem_publisher":"National Fisheries University","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fishu_k_58_65","subitem_relation_type_select":"Local"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00124678","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0370-9361","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Morimoto, Eiji","creatorNameLang":"en"},{"creatorName":"森元, 映治","creatorNameLang":"ja"},{"creatorName":"モリモト, エイジ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Morimoto","familyNameLang":"en"},{"familyName":"森元","familyNameLang":"ja"},{"familyName":"モリモト","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Eiji","givenNameLang":"en"},{"givenName":"映治","givenNameLang":"ja"},{"givenName":"エイジ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2812","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Taira, Yuichiro","creatorNameLang":"en"},{"creatorName":"平, 雄一郎","creatorNameLang":"ja"},{"creatorName":"タイラ, ユウイチロウ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Taira","familyNameLang":"en"},{"familyName":"平","familyNameLang":"ja"},{"familyName":"タイラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Yuichiro","givenNameLang":"en"},{"givenName":"雄一郎","givenNameLang":"ja"},{"givenName":"ユウイチロウ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2839","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Nakamura, Makoto","creatorNameLang":"en"},{"creatorName":"中村, 誠","creatorNameLang":"ja"},{"creatorName":"ナカムラ, マコト","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Nakamura","familyNameLang":"en"},{"familyName":"中村","familyNameLang":"ja"},{"familyName":"ナカムラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Makoto","givenNameLang":"en"},{"givenName":"誠","givenNameLang":"ja"},{"givenName":"マコト","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1908","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40399639","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40399639"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-11"}],"filename":"fishu_k_58_65.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2011928/files/fishu_k_58_65.pdf"},"version_id":"a47f16df-ff6a-4706-ac3c-e2107ed41f1c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fishery engineering;
