Effective method for low-light image enhancement based on the JND and OCTM models
收藏 引用
OPTICS EXPRESS 2023年 第9期31卷 14008-14026页
作者: Lang, Yi-Zheng Wang, Yi-Lun Qian, Yun-Sheng Kong, Xiang-Yu Cao, Yang Nanjing Univ Sci & Technol Sch Elect & Opt Engn Nanjing 210094 Jiangsu Peoples R China
Low-light images always suffer from dim overall brightness, low contrast, and low dynamic ranges, thus result in image degradation. In this paper, we propose an effective method for low-light image enhancement based o... 详细信息
