What is image restoration?

Image restoration is a process aimed at recovering an original image that has been degraded by factors such as noise, blur, or distortions. It involves techniques designed to enhance the quality of an image, making it clearer and more visually accurate. Common methods used in image restoration include filtering, deblurring, and inpainting, often employing algorithms to estimate and reconstruct the lost or corrupted information. The goal is to improve the image's usability for analysis or aesthetic purposes.
