The algorithm improves target object’s signal-to-noise-ratio against background by summing signals along expected streak direction. The signal-to-noise-ratio can be improved with proportional to square root of summed pixel number, theoretically. This algorithm is applied to actual observation datasets to confirm its feasibility. The application test results that the algorithm can detect an object appeared on images as streaks even if pixels’ intensity of each streak are weaker than background noise. It indicates that the algorithm can improve efficiency of geosynchronous object survey conducted by JAXA. The algorithm is applied to actual observation datasets to confirm its feasibility. The test results that the algorithm newly detects three detections correlated to two objects. It is also estimated that the darkest result of the three detections is composed of pixels with low signal intensity 0.66.\"","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AC1500074000","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JSASS-2014-4649","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本航空宇宙学会(JSASS)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Aeronautical and Space Sciences (JSASS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"九州大学"},{"subitem_text_value":"九州大学"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田川, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"花田, 俊也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"柳沢, 俊史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒崎, 裕久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小田, 寛"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tagawa, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hanada, Toshiya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yanagisawa, Toshifumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurosaki, Hirohisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oda, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Orbital Debris","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Observation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Image Processing","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"暗い軌跡を用いた移動物体検出手法の提案","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"暗い軌跡を用いた移動物体検出手法の提案"}]},"item_type_id":"5","owner":"1","path":["1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-10-30"},"publish_date":"2015-10-30","publish_status":"0","recid":"38714","relation_version_is_last":true,"title":["暗い軌跡を用いた移動物体検出手法の提案"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:36:35.679987+00:00"}
