Gradient-based Wiener filter for image denoising
收藏 引用
computerS & ELECTRICAL ENGINEERING 2013年 第3期39卷 934-944页
作者: Zhang, Xiaobo Feng, Xiangchu Wang, Weiwei Zhang, Shunli Dong, Qunfeng Xidian Univ Dept Math Xian 710071 Peoples R China Xianyang Normal Univ Inst Graph & Image Proc Xianyang 712000 Peoples R China
In this paper, we develop a new adaptive image denoising algorithm in the presence of Gaussian noise. Because the proposed method operates in the gradient domain and is close to Wiener filter, it is named as gradient-... 详细信息
