The image process-ing modified the watermark information and we recovered the watermark by the error correction meth-ods. We used the BIT-swapping method for embedding watermark. After image processing, the detec-tion ratio of the watermark was decreased. To correct the patient-ID and institution-ID, we used three type of methods, (1)Bose-Chandhuri-Hocquenghem code, (2)Majority correction method and (3)scramble location method. Once the detection ratio of watermark was decreased to 60%, we could recovery the watermark information. The peak signal to noise ratio was 39 dB at LSB-swapping. We think that these watermarking methods are suitable to the medical images.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"19th International Congress and Exhibition of Computer Assisted Radiology and Surgery (CARS2005)","subitem_description_type":"Other"}]},"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":"Mizuno, Yosuke"}],"nameIdentifiers":[{"nameIdentifier":"669151","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishio, Masato"}],"nameIdentifiers":[{"nameIdentifier":"669152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawashima, Hironao"}],"nameIdentifiers":[{"nameIdentifier":"669153","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ando, Yutaka"}],"nameIdentifiers":[{"nameIdentifier":"669154","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsukamoto, Nobuhiro"}],"nameIdentifiers":[{"nameIdentifier":"669155","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水野 洋輔","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"669156","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安藤 裕","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"669157","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"塚本 信宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"669158","nameIdentifierScheme":"WEKO"}]}]},"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 object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Improvement of digital starting pattern detection and image evaluation of digital watermarked images","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Improvement of digital starting pattern detection and image evaluation of digital watermarked images"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2005-08-17"},"publish_date":"2005-08-17","publish_status":"0","recid":"68151","relation_version_is_last":true,"title":["Improvement of digital starting pattern detection and image evaluation of digital watermarked images"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:29:30.817196+00:00"}
