2005). A reference for image enhancement is the Image Processing Resource kit available in MATLAB (Gonzalez et al., 2020), which implements widely established theoretical principles of digital image processing concepts. Dedicated libraries are also freely available for OpenCv and Python. For instance,...

15 proposed an enhancement technique by applying adaptive gamma correction on the luminosity channel of Lab color space, where the weights are calculated using the cumulative distribution of the histogram of input image pixels. The enhanced image contrast in Lab space is further improved by applying ...
Empirical analyses conducted in environments characterized by Gaussian white noise and natural noise, spanning noise levels 15–50, indicate a marked enhancement in performance. This assertion is quantitatively corroborated by increased average values in metrics such as Peak Signal-to-Noise Ratio (PSNR)...
这篇基于暗通道先验的去雾算法,是何恺明大神 2011 年左右的一篇论文。 理论背景 在计算机视觉和图形学中,会用如下公式来描述模糊图片(hazy image): I表示为获得的图片或者强度,或者说是待去雾的图片;J表示场景光辉,或者说是要恢复的无雾的图片;A表示地球大气中光的成分;t表示非散射光到达相机部分的介质传输。而...
