水平集的快速行进方法,是一种水平集的求解方法,对研究水平集的朋友很有用(This is a method of level set,adopting fast marching. It is very usefull to everyone.)

这个文件可以用来更改matlab生成的界面的标题栏的小山似的图标，换为自己自定义的任何图片(This document can be used to generate matlab change the title bar of the interface of the hill-like icon for their own self-definition for any picture)

实现SC、minn和park算法的度量函数，且求出了均值和方差(The metric function SC, minn and park algorithm, and calculated the mean and variance)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)

航行区域的警示线，在低潮时对水深进行了测量(Navigation area warning line)

说明：  这个是语音信号处理里面的基于MMSE的谱减法增强处理程序，此种方法是我见过消除噪声最好的！(This is the speech signal processing inside the MMSE-based spectral subtraction to enhance handling procedures, this method is the elimination of noise, the best I' ve ever seen!)
