In the proposed method, we reconstruct a 3D surface by estimating the depths of all vertices of a mesh which is composed of piecewise triangular patches on a reference image. We minimize a cost function, which is the sum of each SSD (sum of squared differences) value between a single patch region in the reference image and the corresponding region in the other, by Gauss-Newton optimization. Additionally, we formulate the cost function by incorporating an ICIA (Inverse Compositional Image Alignment) manner for reducing the computational costs of a Hessian matrix in each iteration process. A surface is directly and robustly reconstructed from the images by a hierarchical meshing approach where the surface by a finer mesh is obtained from the initial depths previously estimated by a coarse mesh. The validity of the proposed method is demonstrated through the experiments using synthetic and real images.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"50","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":"38","bibliographicIssueDates":{"bibliographicIssueDate":"2007-11-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG16(CVIM19)","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
