摘要：

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