Unfortunately, to solve the Poisson equations needs large amounts of memory and processing time in case that size of the object to be pasted is large, because some kind of two-dimensional iteration processes are required. In this paper, we present a new technique for fast Poisson image synthesis algorithm using complementary subsampling. Poisson blending is performed on the subsampled image, and the synthesized image is enlarged by a new adaptive interpolation method using gradient information in the original object to be pasted, which can restore high frequency component without blurring. Experimental results show that the proposed method can reduce 90% of the processing time without picture degradation in comparison with conventional synthesis method..","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-07-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"2014-AVM-85"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:47:41.395021+00:00","updated":"2025-01-21T10:50:15.561520+00:00"}
