Multi-scale fusion residual encoder-decoder approach for low illumination image enhancement
《The Journal of China Universities of Posts and Telecommunications》2022年第2期63-72,共10页Pan Xiaoying Wei Miao Wang Hao Jia Fengzhu 
supported by the National Key Research and Development Project(2019YFC0121502);the Graduate Innovation Fund Project of Xi’an University of Posts and Telecommunications(CXJJLY2019062);the Key Laboratory of Network Data Analysis and Intelligent Processing of Shaanxi Province。
The sensing light source of the line scan camera cannot be fully exposed in a low light environment due to the extremely small number of photons and high noise,which leads to a reduction in image quality.A multi-scale...
