Image reconstruction is a field of research that focuses on creating high-quality images from incomplete or noisy data. This can involve restoring images that have been degraded or corrupted in some way, such as through noise, blurring, or missing information. Image reconstruction techniques often involve mathematical algorithms and models that aim to fill in missing information and enhance the quality of the final image. This research area is important in a wide range of fields, including medical imaging, computer vision, remote sensing, and astronomy.
