WebThen, we have determined the mean gray-level value of the all these pixels with gray-levels of the third set which will finally be used as threshold for binarization. A comparison of our results with iterative thresholding [2] and Otsus thresholding [2], [3] is done, and it is evident from the output images that present methodology provides a ... 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. florist in bridgehampton ny
