Firstly, the correspondences between the stereo image pair are obtained. Secondly, each image is warped onto another image and averaged images are generated to reduce noise. Thirdly, an improved correspondences between the noise reduced image pair is obtained to improve the disparity. The iterative computation provides both higher quality images and accurate depth estimation. The method can be extended to the multi-camera stereo to obtain a higher resolution image. Experimental results using both synthetic and real images are shown to demonstrate the effectiveness of the method.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"82","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":"77","bibliographicIssueDates":{"bibliographicIssueDate":"2005-05-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"38(2005-CVIM-149)","bibliographicVolumeNumber":"2005"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":52350,"links":{}}
