As the number of pixels of digital cameras has been increasing, thus the computational cost becomes higher since the order of the filters depends on the image size. There are several acceleration approaches for the edge-preserving filtering; however, most approaches reduce the dependency of filtering kernel size for acceleration. In this paper, we propose a method to accelerate the edge-preserving filters for high-resolution images. The proposed method subsamples an input image and then performs the edge-preserving filtering on the subsampled image. The proposed method then upsamples the subsampled image with the guidance, which is the high-resolution input image. For this upsampling, we generate per-pixel LUTs for high-precision upsampling. Experimental results show that the proposed method has higher performance than the conventional approaches.","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":"2018-11-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2018-AVM-103"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":192377,"created":"2025-01-19T00:58:05.622567+00:00"}
