09 Jul 2012 Image segmentation using Otsu thresholding OTSU(I,N) segments the image I into N classes by means of Otsu's N-thresholding method. Author: Damien Garcia

Thanks a lot for the code!
I just have a question: in the n=2 case, what's the meaning for the following code? I tried to derive the equation, but could not make it. Would you please explain a bit? Thanks!!

sigma2B =...
(mu(end)*w(2:end-1)-mu(2:end-1)).^2./w(2:end-1)./(1-w(2:end-1));
