http://www.iaeng.org/publication/WCE2008/WCE2008_pp694-699.pdf WebThe global thresholding method [24, 25, 36] converts a gray-level image into a binary image based on an image intensity value called global threshold, which is invariant in the whole image domain. For images with an obvious bimodal histogram, global binarization methods are effective.
