methods, there is a non-local median filter. Non-local median filter is excelled in not only noise removal but also detail preserving. In the non-local processing, an output of the filter is calculated from pixels in blocks which are similar to the block centered at a pixel of interest. As a result, aggressive noise removal is conducted without destroying detailed structures in an original image. However, the performance of the non-local median filter decrease enormously when the input image is highly corrupted by the noise. To cope with the problem, we propose an improved non-local median filter which is robust to the high level of corruption by introducing a new similarity measure considering possibility of being original signal. Through the experiments, we verify the effectiveness of the proposed method.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4","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":"2016-08-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2016-AVM-94"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
