Abstract
An image processing method for preparing a document for printing or other further processing. Document images often contain information in several intensity levels. Detecting these levels will help separate logically separate regions in the image. A multithresholding process separates different significant intensity levels in a document image by recursively finding locally optimum threshold locations, and then selecting only the significant thresholds by studying the intensity transitions in the image.
