For this purpose, a set of images of target scene and its depth map are used. We assume that the images are taken from a fixed camera in several lighting conditions, and the depth map is taken from a range finder. A 3D shape model of the scene is roughly constructed from the depth map, and it is reformed by considering the cast shadows in the images. Using the reformed 3D shape, cast shadow contours are corresponded between different lighting conditions. Finally, a cast shadow can be generated in any lighting condition by the image morphing of the cast shadow contours. Experimental results show that shadows can be successfully generated even when the floor is not a flat plane.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"138","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":"130","bibliographicIssueDates":{"bibliographicIssueDate":"2002-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG11(CVIM5)","bibliographicVolumeNumber":"43"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":18105,"links":{}}
