Image Denoising via Asymptotic Nonlocal Filtering
收藏 引用
MATHEMATICAL PROBLEMS IN ENGINEERING 2015年 第1期2015卷 1-9页
作者: Liu, Xiaoyan Feng, Xiangchu Zhang, Xuande Li, Xiaoping Luo, Liang Xidian Univ Sch Math & Stat Xian 710071 Peoples R China Xian Shiyou Univ Sch Sci Xian 710065 Shaanxi Peoples R China Ningxia Univ Sch Math & Comp Sci Yinchuan 750021 Peoples R China
The nonlocal means algorithm is widely used in image denoising, but this algorithm does not work well for high-intensity noise. To overcome this shortcoming, we establish a coupled iterative nonlocal means model in th... 详细信息
