AstroDiff improves astronomical image restoration under atmospheric turbulence by fusing a diffusion-based generative prior with a restoration branch via SGLD, achieving lower LPIPS and BRISQUE than prior learning-based methods.
They are primar- ily due to changes in temperature and pressure, which cause the refractive index of the air to change [1, 2, 3, 4, 5]
