From: Low-light image enhancement via adaptive frequency decomposition network
Visual comparisons on a typical low-light image. Given a low-light RGB image (a), the result obtained by using the existing algorithm is (b,e,f). In comparison, the enhanced images obtained with AFDNet are closer to the ground truth (g) and have good perceptual quality. We apply a Gaussian filter to decompose (b) to obtain the low-frequency information (c) and the high-frequency information (d).
