And we introduce our original approach of a generalized gradient-based method and related studies, which enable to evaluate optical flow under nonuniform and/or non-stationary illumination. The generalized method assumes a conservation law of gray values in the image sequence, and evaluates not only the velocity vector field (optical flow) but also the distribution of non-uniform and/or non-stationary illuminations.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"12","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2008-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG6(CVIM20)","bibliographicVolumeNumber":"49"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
