When a camera is pointed at a strong light source, the resulting photograph may contain lens flare artifacts.
Flares appear in a wide variety of patterns (halos, streaks, color bleeding, haze, etc.) and this … makes flare removal challenging.
Existing … solutions make strong assumptions about the artifact’s geometry or brightness, and therefore only work well on a small subset of flares.
Machine learning … not been widely applied to flare removal due to the lack of training data.
… model … causes of flare either empirically or using wave optics, and generate semi-synthetic pairs of flare-corrupted and clean images. … to train neural networks to remove lens flare
… models trained with our technique generalize well to real lens flares across different scenes, lighting conditions, and cameras.
