LIME is one of the sophisticated night vision algorithms based on Retinex theory. Retinex theory assumes that the image is decomposed into the illumination and the reflectance components. In LIME, the illumination map is estimated by solving optimization problem concerning edge-aware smoothing, and the output image is obtained by adjusting the illumination map. However it tends to cause clipping in the bright regions. In this report, we propose a new low-light image enhancement method based on LIME. In the proposed method, the illumination map is estimated by the soft-closing operation using smoothed local histogram filter. The proposed method can improve the contrast of the image overall while suppressing clipping in bright regions. The effectiveness of the proposed method is verified by experiments using various images.","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":"2021-06-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2021-AVM-113"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T17:43:07.105198+00:00","links":{}}
