Abstract
A method and imaging systems that process images employ image binarization. An image processing system includes a processor, a memory and a computer program stored in the memory and executed by the processor. A scanning system includes a scanner that scans an image source to produce a grayscale image and an image processor that includes a computer program. The respective computer programs include instructions that implement image binarization. The method of image binarization includes generating a solid fills binary image from a grayscale image and generating an edge enhanced binary image from the grayscale image. The method further includes combining the generated binary images to produce a composite binary image and providing the composite binary image as an output binary image.
