Lens Flare

Lens flare, an image artifact caused by light scattering and reflection within a camera lens, degrades image quality and hinders computer vision tasks. Current research focuses on developing effective flare removal methods, primarily employing deep learning models—often based on diffusion models or convolutional neural networks—trained on datasets specifically designed to capture the diverse characteristics of lens flare, including nighttime scenarios. These advancements aim to improve image fidelity and enable more robust performance in applications ranging from photography to autonomous driving, where accurate image interpretation is crucial. The development of more realistic synthetic datasets and improved algorithms that handle multiple light sources and various flare types are key areas of ongoing investigation.
