Multi-frame image restoration method for Luojia 1-01 night-light remote sensing images

To address blur and noise issues caused by airlight atmospheric scattering in nighttime imaging environment, we proposed a multi-frame image restoration method. First, the Luojia 1–01 night-light degradation model was derived. Thereafter, APSF (Atmospheric Point Spread Function) for images estimated. Improved dark channel prior sparse constraint models were used to eliminate effects ofairlight scattering. Finally, established noise. The results show method is effective as it can reduce phenomenon, suppress noise, improve quality.
