Description: 一个新设计的OTSU算法，使用方法如下：％ load clown
％ subplot(221)
％ imshow(X/max(X(:)))
％ title( Original , FontWeight , bold )
％ for n = 2:4
％ Iseg = otsu(X,n)
％ subplot(2,2,n), colormap(gray)
％ imshow(Iseg)
％ title([ n = int2str(n)], FontWeight , bold )
％ end

％ end-OTSU design a new algorithm, using the method as follows: load clown subplot (221) imshow (X/max (X (:))) title (Original, FontWeight, bold) for n = 2:4 Iseg = otsu (X, n) subplot (2,2, n), colormap (gray) imshow (Iseg) title ([n = int2str (n)], FontWeight, bold) end
