Abstract
Image restoration technology is a technology that uses the visible information on the current image or another image to fill in the occluded or damaged area on the image, so as to obtain a visually satisfactory effect. This paper proposes a multi-granular distortion correction algorithm, a The coarse-to-fine distortion correction algorithm performs perspective distortion correction on the image perspective and then is used to complement the damaged area on the target image. Finally, the Poisson imaged fusion algorithm is used to eliminate the ghost phenomenon between the repaired area and its surrounding pixels, To obtain a seamless repair effect. Experiments prove that the algorithm has obvious reliability.
