中文说明：形态学滤波、最大均值和最大中值滤波算法，是弱小目标检测的典型算法。形态学滤波算法是一种有效的图像预处理算法，其基本思想是利用具有一定形态的结构元提取图像中对应的形态以实现对图像的分析和识别。它能够简化图像数据，保持图像的基本特性，并去除不相干的图像结构。最大均值和最大中值滤波法结构简单，易于实现，但它所使用的窗口尺寸和形状对背景抑制效果影响较大。二维最小均方误差算法(TDLMS)是一种具有良好滤波效果的图像预处理算法，它的基本思想是根据图像中背景邻域的相关性和目标的奇异性，利用最小均方误差准则t估计出邻域中心像素的背景预预4值，并根据该预测值与原始图像的残差对加权系数矩阵进行修正，从而使得算法具有一定的自适应性
English Description：
Morphological filtering, maximum, mean and maximum median filtering algorithm, is typical of Dim target detection algorithm. Morphological filtering algorithm is an efficient algorithm for image pre-processing, the basic idea is to use a certain form of structure element from the corresponding shape in the image in order to image analysis and pattern recognition. It can simplify the image data, maintaining the basic characteristics of the image, and remove irrelevant image structure. Maximum average and maximum value filter structure is simple, easy to implement, but the size and shape of the window used for background suppression effect of great impact. II dimension minimum are party errors algorithm (TDLMS) is a has good filtering effect of image pretreatment algorithm, it of basic thought is according to image in the background o domain of correlation and target of singular sex, using minimum are party errors guidelines t estimated out o domain Center pixel of background pre pre 4 v
