摘要：A method of recognizing characters in a document image comprises examiningthe 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 theforeground from background in the document image as a function of the identified peakintensity is determined. The document image is thresholded using the threshold level toidentify the foreground. Character recognition is performed on the foreground of thedocument image, based on edge orientations and edge magnitudes.
