matlab .m computes a segmented image Otsu's n-thresholding

Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes by means of Otsu's n-thresholding method (Otsu N, A Threshold Selection Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern. 9:62-66;1979). Thresholds are computed to maximize a separability criterion of the resultant classes in gray levels.
