此程序提供两种一维信号信息熵的计算方法，其中一种是近似信息熵计算，可以有效的识别信号的复杂度(This program provides two kinds of one-dimensional signal and the calculation method of information entropy is one kind of approximate entropy calculation, can effectively identify the complexity)

改程序包里包含中值、均值滤波、自适应中值滤波和一种改进的椒盐噪声滤波程序，前三种是给第四种作对比的，第四种方法对椒盐滤除效果很好。(Change the program package contains the value, mean filtering, adaptive median filter and an improved impulse noise filtering program is the first three compare to the fourth, the fourth method works well for removing salt and pepper.)
