OTSU Gray-level image segmentation using Otsu s method. 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. OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the corresponding Iseg is therefore a binary image. The pixel values for Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ... [Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability criterion within the range [0 1]. Zero is obtained only with images having less than n gray level, whereas one (optimal value) is obtained only with n-valued images.

说明：  pm调制，该仿真有助于相位调制,这是模拟调制方面的知识(pm modulation, the simulation will help phase modulation, which is knowledge of analog modulation)

说明：  切普信号生成，可以改变信号的起始频率和最终频率。(Be able to generate a linear-FM “chirp” signal that sweeps in frequency fromω1 = 2pi*f1 to ω1 = 2pi*f2 as time goes from t = 0 to T2. You can change any of these values.)
