a posteriori estimate meaning in English

后验估值

3 , on the base of the traditional spatial filtering , the author present , a new despeckle algorithm , that make use of iterated processing and correlated neighbourhood model , iterated filtering method of the sar image combining the correlated neighbourhood model with maximum a posteriori filter . first , a series of templates refecting direction information are established and every template is present for a kind of neighbour structure . then on the basis of sar images statistical property , the maximum a posteriori estimate of the real intensity under observation image values is got by bayes formulatio - n
3 、针对传统空间滤波器的不足，引入迭代处理和相关邻域模型的概念，提出了基于相关邻域模型的最大后验迭代滤波。该算法引用一系列反映局部边界特征的邻域模型，以描述图像的细节。引入强度的先验概率分布模型，利用bayes方法，对各个结构进行实际强度的最大后验估计。
