wireshark 抓取pacp包进行分析 判断延迟 丢失等(wireshark packet analysis grab pacp judge delayed loss, etc.)

自己写的costas信号程序，需要的可以下载(I wrote it myself costas. A friend in need can be downloaded.)

对信号进行小波包分解，得出能量分布图，然后根据分解结果处理信号！(Wavelet packet decomposition of signals obtained energy distribution and signal processing based on decomposition!)

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.
