Abstract

The invention relates to correcting page curl in scanned books. A computer implemented method for correcting distortion in an image of a page includes identifying a set of high quality (HQ) words in undistorted regions of one or more images of pages having content related to the content of the page. At least one distorted word in the image the page is identified such that each distorted word corresponds to a high quality word of the set. A global transformation function is generated for application to the image of the page so as to tranform the distorted word into its corresponding high quality word. The global transformation function is applied to pixels of the image of the page.

Description

technical field [0001] The present invention relates to digitization of books. More specifically, the invention relates to correcting digital scan data for curled pages, such as near the spine of a book, or other distortions of the page. Background technique [0002] Printed materials contain a great deal of information. Printed materials may include books as well as newspapers, periodicals, magazines, brochures and other periodical literature. However, access to and storage space for such materials is often limited. For example, due to the rarity and (often) fragility of certain materials (such as some older books and publications), institutions that preserve said materials (such as libraries, museums, or private owners) may not Willing to lend books to individuals or other institutions. Accordingly, a researcher or other interested individual wishing to access such material may have to travel to the location of the material. Even so, access may be limited to a limited...
