FLASH/NO-FLASH IMAGING FOR BINARIZATION

摘要

Provided are methods and systems for generating a binarized representation of a document using a mobile device configured to provide a Flashed and No-flashed image of the document. According to an exemplary method, the Flash and No-flash images are aligned and blended, where the resulting image includes the No-flash image where any hot spots are included in the Flash image.
