Flare presence and light source
All benchmark models struggle to restore scenes with flare compared to those without flare. The severity of degradation within flare-present scenes varies based on the light source (e.g., natural sunlight, artificial light, or both). Intense sunlight can oversaturate pixel values, making objects around the flares less visible. Consequently, the benchmark models have more difficulty restoring videos with flares caused by natural sunlight than those caused by artificial light. This distinction in the impact of different light sources on restoration performance is a significant finding of this research.
