In the proposed method, we reconstruct a 3D surface by estimating the depths of all vertices of piecewise triangular patches which composes a mesh generated on the reference image. We express the SSD (sum of squared differences) value between a single patch region in the reference and the corresponding region in the input as a function of three depths of the vertices of the patch. Then all depths are estimated by minimizing the accumulated SSD value with respect to all patches by Gauss-Newton optimization. For reducing the iterative computational costs for depth estimation, we incorporate an ICIA (inverse compositional image alignment) manner for expressing the SSD function. The validity of the proposed method is shown by some experiments using synthetic and real images.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"116","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":"109","bibliographicIssueDates":{"bibliographicIssueDate":"2006-11-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"115(2006-CVIM-156)","bibliographicVolumeNumber":"2006"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:16:31.406788+00:00","updated":"2025-01-22T06:55:24.854235+00:00"}
