Abstract
A recent segmentation method that uses transition regions to select an appropriate threshold for binarization is compared to an older averag ed gradient thresholding method. It is shown that these methods are cl osely related to each other. We also show that this relation enables u s to relieve some of the problems concerning edge-based thresholding.
