1. A method for detecting distortion in an input image of a scanned book, the input image being one of a digitized image stored in a memory or a scanned image from a scanner, comprising: using a processor to divide the input image into a plurality of blocks of pixels; associate each block of pixels in the input image with a pixel in a feature image; analyze values of each pixel in the feature image to create a binary map of the feature image, wherein each pixel in the binary map corresponds to a page area or not a page area; subject the binary map to object segmentation to group binary map pixels corresponding to a page area; create a set of page objects; detect borders of the page area; and detect distortion within the page area.
