1. An image processing method for generating an image from a hard copy document, comprising: (a) scanning the hard copy document multiple times using a scanner to generate a plurality of images; (b) performing deskewing for each image; (c) performing translational compensation for each image; (d) selecting two images among the plurality of images that have the highest similarity to each other, the two selected images including a first image and a second image; (e) dilating the first image; (f) converting the dilated first image into a binary form; (g) eroding the converted first image to generate a first processed image; (h) eroding the second image; (i) converting the eroded second image into a binary form; (j) dilating the converted second image to generate a second processed image; (k) extracting common portions of the first and second processed images to generate a final image; and (l) storing the final image.
