Abstract
The invention provides various methods and techniques for binarizing an image, generally in advance of further processing such as optical character recognition (OCR). One step includes establishing boundaries of image objects of an image and classifying each image object as either suspect or non-suspect. Another step includes creating a local binarization threshold map that may include or store threshold binarization values associated with image objects classified as non-suspect. Yet another step includes expanding the local binarization threshold map to cover the entire image thereby creating a global binarization threshold map for the entire image. The methods and techniques are capable of identifying and working with separation objects and incuts in images.
