Super-resolution is a technique to remove the noise of observed images and restore the high frequencise of ones. We focus on reconstruction-based super-resolution because it can restore their own brightnesses. It produces a highresolution image from a set of low-resolution images. Reconstruction requires large computation cost because it requires many images. However, it is necessary to improve arithmetic circuits’ performance specific to reconstruction-based super-resolution since the reconstruction-based algorithms need more information on images. In this paper, we propose a reconstruction-based super-resolution using a weighted adder. Our weighted adder is implemented by using selector logics so that we can reduce carry propagations and improve the performance of reconstruction-based super-resolution. Finally, experimental results demonstrate that our proposed weighted adder circuit improves the performance by 13 % and reduces the area by 32 %, compared to conventional weighted adders.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムLSI設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-05-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2011-SLDM-150"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:31:43.708594+00:00","id":73977,"links":{}}
