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 、針對傳統空間濾波器的不足，引入迭代處理和相關鄰域模型的概念，提出了基於相關鄰域模型的最大后驗迭代濾波。該演算法引用一系列反映局部邊界特徵的鄰域模型，以描述圖像的細節。引入強度的先驗概率分佈模型，利用bayes方法，對各個結構進行實際強度的最大后驗估計。 -
Let { xn ; n > 1 } be mutually identically independent random variables distributed according to the normal distribution, { sn, n > 1 } be finite partial sum series, the purpose of this paper is to investigate law of the iterated logarithm type results for special finite partial weight sum series { sn, n > 1 }, we assume that sn = a1sn + a2 ( s2n - sn ) + a3 ( s3n - s2n ) +. . + ad ( sdn - s ( d - 1 ) n ) in the second chapter, theory 2 by using the method of literature [ 8 ], we extend hartman - wintner law of iterated logarithm on the gauss distribution. we substitute negative correspond for independent. it extends the corresponding results in gauss distribution
設{ x _ n ； n 1 }是獨立同分佈的且服從標準正態分佈的隨機變量序列， { s _ n ， n 1 }是其部分和數列，討論有限項特殊加權部分和{ s _ n ， n 1 }的重對數律，其中定理2利用文獻[ 8 ]提供的方法，在高斯分佈上改進了hartman - wintner的重對數律，取消獨立性用更弱的條件負相關代替，大大拓寬了重對數律在高斯分佈中的使用范圍。
