We assume that all digit images are of the same size and obtain one color histogram for each pixel by counting the number of occurrences of each color over multiple images. For example, when we conduct the counting over the images of digit \"5\", we obtain a set of histograms as a prototype of digit \"5\". After normalizing each histogram to a probability distribution, we can classify an unknown digit image by multiplying probabilities of the colors appearing at each pixel of the unknown image. We regard this method as the baseline and compare it with a method using our probabilistic model called Multinomialized Subset Infinite Relational Model (MSIRM), which gives a prototype, where color histograms are clustered column- and row-wise. The number of clusters is adjusted flexibly with Chinese restaurant process. Further, MSIRM can detect irrelevant columns and rows. An experiment, comparing our method with the baseline and also with a method using Dirichlet process mixture, revealed that MSIRM could neatly detect irrelevant columns and rows at peripheral part of digit images. That is, MSIRM could \"trim\" irrelevant part. By utilizing this trimming, we could speed up classification of unknown images.","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"FTRA 7th International Conference on Multimedia and Ubiquitous Engineering, MUE 2013; Seoul; South Korea; 9 May 2013 through 11 May 2013","subitem_description_type":"Other"}]},"item_9_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Lecture Notes in Electrical Engineering, 240, pp.129-134; 2013","subitem_description_type":"Other"}]},"item_9_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Verlag"}]},"item_9_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/978-94-007-6738-6_16","subitem_relation_type_select":"DOI"}}]},"item_9_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2013 Springer Science+Business Media Dordrecht(Outside the USA)"}]},"item_9_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18761100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"18761119","subitem_source_identifier_type":"ISSN"}]},"item_9_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Masada, Tomonari"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takasu, Atsuhiro"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"LNEE240_129.pdf","filesize":[{"value":"379.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"LNEE240_129.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/6725/files/LNEE240_129.pdf"},"version_id":"f58381af-4caf-4164-883d-431f45c80701"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bayesian nonparametrics","subitem_subject_scheme":"Other"},{"subitem_subject":"Classification","subitem_subject_scheme":"Other"},{"subitem_subject":"Prototype","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Trimming Prototypes of Handwritten Digit Images with Subset Infinite Relational Model","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Trimming Prototypes of Handwritten Digit Images with Subset Infinite Relational Model"}]},"item_type_id":"9","owner":"2","path":["65"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-01"},"publish_date":"2014-06-01","publish_status":"0","recid":"6725","relation_version_is_last":true,"title":["Trimming Prototypes of Handwritten Digit Images with Subset Infinite Relational Model"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T02:39:14.437804+00:00"}
