However, tracking the underlying continuous behavior of the 3D tensor fields is still challenging due to the lack of appropriate interpolation schemes that can avoid unexpected swelling effects. This report presents an approach to interpolating such 3D diffusion tensor fields by respecting the underlying anisotropic structure of the given datasets. The main idea behind our approach is to alleviate swelling effects by optimizing the rotational transformation between a pair of tensors through the eigenanalysis of associated matrix representations. Comparisons with existing interpolation schemes will be provided to clarify the advantages of the proposed approach together with several visualization results of 3D medical tensor fields.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"72","bibliographic_titles":[{"bibliographic_title":"研究報告グラフィクスとCAD（CG）"}],"bibliographicPageStart":"67","bibliographicIssueDates":{"bibliographicIssueDate":"2009-02-09","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12(2009-CG-134)","bibliographicVolumeNumber":"2009"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:23:32.792283+00:00","id":61326,"links":{}}
