地震波处理并画图，matlab编程的小程序(Seismic processing and drawing, matlab programming, small programs)

说明：  按照全赛一等奖论文中叙述的算法编写，含有C和MATLAB两种程序(In accordance with the competition the first prize paper describes an algorithm written in MATLAB with C, and two procedures)

通过计算短时信号熵，与阈值比较，得到判决结果。并采用顺序统计滤波器（最大值滤波器）对所得熵值滤波，提高判决精度。 能有效的分辨出语音信号和噪声信号，且通过后端平滑处理，使语音检测结果更加集中。(VAD based on short-time entropy, precision improved by using order-statistical-filter, VAD result is smoothed to make the result more accurate.)
