Residual dense U-Net for abnormal exposure restoration from single images
收藏 引用
IET image processing 2021年 第1期15卷 115-126页
作者: Que, Yue Lee, Hyo Jong Jeonbuk Natl Univ Div Comp Sci & Engn Jeonju 54896 South Korea Jeonbuk Natl Univ Ctr Adv Image & Informat Technol Jeonju South Korea
Digital imaging devices sometimes capture images with abnormal exposure because of the complex lighting conditions and limited dynamic range of luminance. In this work, a new residual dense U-Net is proposed to predic... 详细信息
