WitrynaBW = imbinarize (I) creates a binary image from 2-D or 3-D grayscale image I by replacing all values above a globally determined threshold with 1 s and setting all other values to 0 s. By default, imbinarize uses Otsu's method, which chooses the threshold value to minimize the intraclass variance of the thresholded black and white pixels [1 ...
