WebBW = 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 ... Web% BW = IM2BW(X,MAP,LEVEL) converts the indexed image X with colormap MAP to % black and white. % % BW = IM2BW(RGB,LEVEL) converts the RGB image RGB to black and white. % % Note that the function GRAYTHRESH can be used to compute LEVEL % automatically. % % Class Support %----- % The input image can be uint8, uint16, single, …
