High-contrast imaging is a field of research focused on developing methods and technologies to enhance the visibility of objects that are much fainter or located close to bright sources in images. This is particularly important in astronomical imaging, where researchers need to isolate and study faint planets, stars, or other objects in the presence of bright stars or glare. High-contrast imaging techniques involve using advanced optics, signal processing algorithms, and adaptive optics to improve image quality and reduce background noise, allowing for clearer and more detailed observations of dim objects in challenging environments. This research area has applications in astronomy, microscopy, and medical imaging, among others.
