We already have such a method based on a traditional DP matching algorithm, and this article proposes two distance approximation algorithms improved in computation time from the original algorithm. One approximation algorithm realizes pruning in a way of reserving local optimization paths. Another approximation algorithm narrows the search area in DP matching in a way of noticing feature points. Experimental results show that these two algorithms can decrease computation time without decreasing precision of distance measurement.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"170","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"165","bibliographicIssueDates":{"bibliographicIssueDate":"2004-09-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"91(2004-CVIM-145)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
