Recent research has shown that human perceptually better super resolution is possible by training models with additional loss functions such as adversarial loss and VGG loss, in addition to reconstruction errors such as L1 and L2 loss. Such perceptual super resolution has been extensively studied in image super resolution, but less so in video super resolution. The purpose of this study is to elucidate the effect of training data on the perceptual quality of video super resolution in such perceptual video super resolution. Specifically, we will learn by clustering training data by various indices, analyze the performance of the resulting super resolution models, and clarify the relationship between them.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-05-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"39","bibliographicVolumeNumber":"2022-CVIM-230"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":217852,"updated":"2025-01-19T15:21:27.979061+00:00","links":{},"created":"2025-01-19T01:18:16.802265+00:00"}
