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-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

Description: Generate a 3D point plot of L=(x,y,z) using the values in the vector c to
determine the color of each point. If c is empty, then z (column 3 of L)
is used to color the plot. The data points are sorted so that plot3 is
only called once for each group of points that map to the same color. The upper and lower limits of the color range (and the z axis) can be defined with crange. This is useful for creating a series of plots with the same
coloring. The colormap (but not the colorbar) is flipped upside down if
crange is given as [max min] instead of [min max]. The figure handle is
returned if an output argument is given.-Generate a 3D point plot of L=(x,y,z) using the values in the vector c to
