This trend indicates that aquaculture industry has to create a new technique to enlarge economic scale with reducing production cost and increasing production efficiency. Optimizing fish feeding process is the most influential aspect because the process itself takes up to 40 percent of total production cost. Automatic controlling fish feeding in real environment is still challenging problem and active research in aquaculture field because experienced fishermen can adequately control fish feeding machine based on assumption of ripple behavior and duration of fish feeding process. To build robust method which is reasonable application, we propose automatic controlling fish feeding machine based on computer vision using combination of two feature extractions which counts number of nutriments and estimates ripple behavior using regression and textural feature, respectively. To count number of nutriments, we apply object detection and tracking methods to acknowledge the nutriments moving to sea surface. Recently, object tracking is active research and challenging problem in applications of computer vision. Unfortunately, the robust tracking method for multiple small objects with dense and complex relationship is still challenging problem in aquaculture field with more appearance creatures. Assuming that degree of hunger can be represented by behavior of ripple area, estimation of ripple behavior is defined by human assumption of which the size and number of ripple can be used to adjust the activity level of ripple. Based on the number of nutriments fed and ripple behavior, we can control fish feeding machine which consistently performs well in real environment datasets. In evaluation, the proposed method presents the agreement for automatic controlling fish feeding by the activation graphs of regression and textural feature of ripple behavior results. Our tracking method can precisely track the nutriments in next frame comparing with other methods. Based on computational time, proposed method reaches 3.86 fps while other methods spend lower than 1.93 fps. Quantitative evaluation can give promising that the proposed method is valuable for aquaculture fish farm with widely applied to real environment datasets.","subitem_description_type":"Abstract"}]},"item_20_description_5":{"attribute_name":"備考","attribute_value_mlt":[{"subitem_description":"九州工業大学博士学位論文 学位記番号：生工博甲第421号 学位授与年月日：令和3年9月24日","subitem_description_type":"Other"}]},"item_20_description_60":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_description":"令和3年度","subitem_description_type":"Other"}]},"item_20_dissertation_number_62":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第421号"}]},"item_20_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18997/00008660","subitem_identifier_reg_type":"JaLC"}]},"item_20_text_34":{"attribute_name":"アドバイザー","attribute_value_mlt":[{"subitem_text_value":"堀尾, 恵一"}]},"item_20_version_type_63":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"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":[{"creatorNames":[{"creatorName":"Muhamad Hilmil Muchtar Aditya Pradana","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-12-20"}],"displaytype":"detail","filename":"sei_k_421.pdf","filesize":[{"value":"18.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sei_k_421.pdf","objectType":"fulltext","url":"https://kyutech.repo.nii.ac.jp/record/7456/files/sei_k_421.pdf"},"version_id":"e4d7f12b-936f-41aa-8c6d-f1a37873524f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Production Efficiency","subitem_subject_scheme":"Other"},{"subitem_subject":"Fish Feeding","subitem_subject_scheme":"Other"},{"subitem_subject":"Ripple Behavior","subitem_subject_scheme":"Other"},{"subitem_subject":"Textural Feature","subitem_subject_scheme":"Other"},{"subitem_subject":"Tracking","subitem_subject_scheme":"Other"},{"subitem_subject":"Multiple Small Objects","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Trajectory Mapping Based-Object Tracking and CNN Based-Textural Feature Extraction for Application to Aquaculture","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Trajectory Mapping Based-Object Tracking and CNN Based-Textural Feature Extraction for Application to Aquaculture","subitem_title_language":"en"},{"subitem_title":"養殖魚給餌システムのための軌跡マッピングに基づく追跡とCNNに基づくテクスチャー特徴抽出","subitem_title_language":"ja"}]},"item_type_id":"20","owner":"18","path":["7"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-12-20"},"publish_date":"2021-12-20","publish_status":"0","recid":"7456","relation_version_is_last":true,"title":["Trajectory Mapping Based-Object Tracking and CNN Based-Textural Feature Extraction for Application to Aquaculture"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-08-05T09:37:32.572685+00:00"}
