Web19 jul. 2024 · Images taken in low light lack colors and distinctive edges. This makes it very difficult to use them for any computer vision tasks or even for personal use. Web1 sep. 2024 · Low-light images are not conducive to human observation and computer vision algorithms due to their low visibility. To solve this problem, many image enhancement techniques have been proposed. However, existing techniques inevitably introduce color and lightness distortion when increasing visibility.

WebImages captured in low-light conditions are prone to suffer from low visibility, which may further degrade the performance of most computational photography and computer vision applications. In this paper, we propose a low-light image degradation model derived from the atmospheric scattering model, which is simple but effective and robust. Then, we …
