In addition, since the latitude is high, visible channels cannot be used during winter. In this paper, a method to extract clouds using only NOAA/AVHRR channel 4 is proposed. Using geographical information, the AVHRR image was first segmented into two regions : sea and land. Afterward, cloud extraction was performed for each region separately by minimum distance classifier using image features. To improve the error rate of the classification, we apply thresholds to the discriminant function used by the Mahalanobis classifier.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002871","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA1129795X","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":"Faculty of Engineering, Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1998-11-01"}],"displaytype":"detail","filename":"KJ00002364381.pdf","filesize":[{"value":"942.7 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002364381","url":"https://nipr.repo.nii.ac.jp/record/2871/files/KJ00002364381.pdf"},"version_id":"f16d8511-23f3-4e89-a515-d177fd6b2075"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"CLOUD EXTRACTION FROM POLAR SATELLITE DATA USING MODIFIED MAHALANOBIS CLASSIFIER","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CLOUD EXTRACTION FROM POLAR SATELLITE DATA USING MODIFIED MAHALANOBIS CLASSIFIER"}]},"item_type_id":"1","owner":"4","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"1998-11-01"},"publish_date":"1998-11-01","publish_status":"0","recid":"2871","relation_version_is_last":true,"title":["CLOUD EXTRACTION FROM POLAR SATELLITE DATA USING MODIFIED MAHALANOBIS CLASSIFIER"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:41:20.133508+00:00"}
