"Dynamic Thresholding of Grey-Level Images," Proceedings of ... WebIn this article, a granular computing based multi-level gray image thresholding algorithm is presented. An image is divided into spatial blocks called granules, and the classes of gray levels are represented using a fuzzy-rough collaborative approach, where the measure of roughness of a rough set is also modified from the classical definition of rough sets.

WebJan 8, 2013 · Here, the matter is straight-forward. For every pixel, the same threshold value is applied. If the pixel value is smaller than the threshold, it is set to 0, otherwise it is set to a maximum value. The function cv.threshold is used to apply the thresholding. The first argument is the source image, which should be a grayscale image. The second ... 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.
