用MATLAB作的一个滤波程序 (MATLAB for a filtering process ///////////////////// )

克里金法广泛地应用于地下水模拟、土壤制图等领域，是一种很有用的地质统计格网化方法。它首先考虑的是空间属性在空间位置上的变异分布．确定对一个待插点值有影响的距离范围，然后用此范围内的采样点来估计待插点的属性值。该方法在数学上可对所研究的对象提供一种最佳线性无偏估计(某点处的确定值)的方法。它是考虑了信息样品的形状、大小及与待估计块段相互间的空间位置等几何特征以及品位的空间结构之后，为达到线性、无偏和最小估计方差的估计，而对每一个样品赋与一定的系数，最后　进行加权平均来估计块段品位的方法。(Kriging is a technique that provides the Best Linear Unbiased Estimator of the unknown fields (Journel and Huijbregts, 1978 Kitanidis, 1997). It is a local estimator that can provide the interpolation and extrapolation of the originally sparsely sampled data that are assumed to be reasonably characterized by the Intrinsic Statistical Model (ISM). An ISM does not require the quantity of interest to be stationary, i.e. its mean and standard deviation are independent of position, but rather that its covariance function depends on the separation of two data points)

FILLNANS replaces all NaNs in array using inverse-distance weighting between non-NaN values.

Imagescn plot two or more imagesc into the same axes. Deeper layers are visible, were higher layers have the value NaN. This is helpful e.g. to show measurement (=foreground) results "above" a map (=background), to separate NaN values within a 2D matrix from the lowest value (standard image shows the same color at NaN as it does for the lowest value). The number of layers is only limited by memory space :-).(Piled images Imagescn plot two or more imagesc into the same axes. Deeper layers are visible, were higher layers have the value NaN.

很详细地介绍了matlab在图像处理中的应用，其中有车牌号的识别，染色体的识别等，还有文档说明，精心整理的，希望和大家分享！(Very detailed description of the matlab in image processing applications, including license plate number recognition, chromosome identification, as well as documentation and careful finishing, and would like to share!)

本文根据对原始纯净图像进行的椒盐加噪处理，提出了利用中值滤波法消除图像噪声的实用方法。使用软件工具MATLAB快速地实现了图像的中值滤波。(According to the original purity of the salt and pepper plus noise image processing, proposed by using median filter to reduce image noise and practical method. MATLAB software tools used to achieve fast median filtering of images.)
