An Approach for Scratch Removal from Digital Image using Image Reconstruction

Abstract

Old digital pictures or scanned images of old paper based images tend to have annoying scratches. This effects the overall quality of the image, both quantitively and visually. To remove these scratches and to generate a perfect noise and scratch free image, a novel method is presented in this paper. This approach not only detects scratches in an image but also removes them effectively. The method starts with a scratched digital version of an image then it removes noises after which region of scratch are identified. Filtering is an important step in this proposed method. Here filtering is a two level process after which a specific superimposing method is been applied to reconstruct the scratch and noise free image.
