Matching Pursuit 算法是信号分解的一种具体实现方法。但其本质上则是一种估计 信号模型参数的方法，因而可直接用于信号检测及参量估计。本文以谐波信号特征参量的估计为例，介绍了其具体实现方法。(Matching Pursuit algorithm is a specific method of signal decomposition. But by its very nature is an estimated signal model parameters, and thus can be directly used for signal detection and parameter estimation. In this paper the harmonic signal characteristics of the estimates of the parameters, for example, describes the specific implementation method.)

中值滤波窗口大小影响滤波器性能,3×3滤波窗口可以很好地保持图像细节。提出一种新的自适应中值滤波方法。将3×3窗口中心的极值点作为候选噪声点,若候选噪声点仍然是7×7窗口的极值点,则该点即是噪声点。若以噪声点为中心的3×3滤波窗口的中值不是噪声,则噪声用中值替换。重复以上过程,直到没有噪声点被替换。(Median filter window size affect the filter performance, 33 filter window can be well preserving image detail. Propose a new adaptive median filtering method. The 33 extreme point of the center of the window as the candidate noise the candidate noise is still 77 extreme points of the window, the point is that the noise point. Terms of noise centered on the point 33 filtering window value is not a noise, the noise is replaced with the median. The process is repeated until there is no noise point is replaced.)

求相对误差，在知道标准值以及实验室的情况下，采用matlab编程求出相对误差并分析结果。(Demand relative error)
