We show that the recently proposed method of matrix log-cumulant may lead to non-invertible equations and cause unstable performances. In order to overcome such difficulty, we proposed a Bayesian-based method to re-estimate the log-cumulants. Simulation experiment demonstrates that the proposed algorithm provides both improved and stabler results. Finally, we present an application of the new method for texture analysis of the Germany F-SAR polarimetric data.", "subitem_description_type": "Abstract"}]}, "item_8_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_8_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ap-s.ei.tuat.ac.jp/isapx/2013/pdf/305_3_0.pdf", "subitem_relation_type_select": "URI"}}]}, "item_8_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright(C)2013 IEICE"}, {"subitem_rights": "本文データは学協会の許諾に基づきホームページから複製したものである"}]}, "item_8_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Cui, Yi"}], "nameIdentifiers": [{"nameIdentifier": "168847", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamada, Hiroyoshi"}], "nameIdentifiers": [{"nameIdentifier": "50", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamaguchi, Yoshio"}], "nameIdentifiers": [{"nameIdentifier": "19", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ISAP2013_TA-1(D)-3.pdf", "filesize": [{"value": "3.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 3000000.0, "url": {"label": "ISAP2013_TA-1(D)-3.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/30903/files/ISAP2013_TA-1(D)-3.pdf"}, "version_id": "26a0090a-f89a-46d9-8dde-49e5a709bdd5"}]}, "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": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "Stable Parameter Estimation of Compound Wishart Distribution for Polarimetric SAR Data Modeling", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Stable Parameter Estimation of Compound Wishart Distribution for Polarimetric SAR Data Modeling"}]}, "item_type_id": "8", "owner": "1", "path": ["457", "1822"], "permalink_uri": "http://hdl.handle.net/10191/30816", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-04"}, "publish_date": "2014-12-04", "publish_status": "0", "recid": "30903", "relation": {}, "relation_version_is_last": true, "title": ["Stable Parameter Estimation of Compound Wishart Distribution for Polarimetric SAR Data Modeling"], "weko_shared_id": 2}
