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. WebNov 18, 2013 · 1. cv2.inRange (src, lowerb, upperb [, dst]) → dst. Takes src as array and lower and upper as array or a scalar, this means you can use it to Threshold Grayscale images. You just have to use scalars for upper and lower. Example: myResult = cv2.InRange (myGrayscale, 50, 100) Share. Improve this answer.
