High-dynamic-range imaging for cloud segmentation [PDF]
Atmospheric Measurement Techniques, 2018 Sky–cloud images obtained from ground-based sky cameras are usually captured using a fisheye lens with a wide field of view. However, the sky exhibits a large dynamic range in terms of luminance, more than a conventional camera can capture. It is thus

Single-Shot High Dynamic Range Imaging via Multiscale Convolutional Neural Network
IEEE Access, 2021 We propose a single-shot high dynamic range (HDR) imaging algorithm with row-wise varying exposures in a single raw image based on a deep convolutional neural network (CNN). We first convert a raw Bayer input image into a radiance map by calibrating rows
