The blurring process can be modeled as an image convolution by point spread function (PSF) which describes the motion path. A deblurring from a single blurred image is challenging problem, even if the PSF is known. The deblurred images usually include unexpected ringing artifacts. In this paper, we proposed a progressive image deconvolution method using a residual image. In the proposed method, the input blurred image is decomposed into the reference image and the residual image. Then, the blurred residual image is deblurred instead of the input blurred image. The reference image is updated based on the deblurred residual image. We demonstrate the effectiveness of the proposed method using synthetic images and real images.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"104","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":"99","bibliographicIssueDates":{"bibliographicIssueDate":"2008-05-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"36(2008-CVIM-163)","bibliographicVolumeNumber":"2008"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":51813,"links":{}}
