  • Method And Apparatus For Recognizing Characters In A Document Image
    Publication number: 20080310721
    Abstract: A method of recognizing characters in a document image comprises examining the intensity of pixels in the document image and identifying a peak intensity deemed to represent foreground in the document image. A threshold level for distinguishing the foreground from background in the document image as a function of the identified peak intensity is determined. The document image is thresholded using the threshold level to identify the foreground. Character recognition is performed on the foreground of the document image.
