Abstract
A system creates an electronic version of a document from page-images of the document, wherein the electronic version replicates both the logical content and the physical appearance of the original document. During operation, the system receives the page-images for the document. Next, the system extracts character images from the page-images, and generates a synthetic font for the document from the extracted character images. Finally, the system constructs the electronic version of the document by, using the synthetic font to represent text regions of the document, and by using image-segments extracted from the pages-images to represent non-text regions of the document.
