Multilevel image thresholds using Otsu’s method - MathWorks
WebGlobal image threshold using Otsu's method collapse all in page Syntax T = graythresh (I) [T,EM] = graythresh (I) Description example T = graythresh (I) computes a global threshold T from grayscale image I, using Otsu's method [1] . Otsu's method chooses a threshold that minimizes the intraclass variance of the thresholded black and white pixels. Webthresh = multithresh (A) returns the single threshold value thresh computed for image A using Otsu’s method. You can use thresh as an input argument to imquantize to convert an image into a two-level image. example thresh = multithresh (A,N) returns thresh a 1-by-N vector containing N threshold values using Otsu’s method.
