despeckle meaning in Chinese
和去除杂点
可以模糊图象中除边缘外的区域，这种模糊可以去掉图象中的杂色同时保留细节。
去斑
去班
去除噪点
Examples
- Despeckle removes speckles or small imperfections from an entire image
去除斑点消除整幅图像中的斑点或一小部分不理想之处。 - 2 , the author analyses and derives the more famous despeckle algorithm and has already made a program to implement these algorithms .
2 、分析和推导了一些比较重要的相干斑抑制算法，并编程实现了这些算法。 - 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。 - Under a unified frame , different despeckling sub - algorithms are designed to despeckle different kinds of regions : a modified acmap algorithm ( simulated annealing correlated neighborhood map despeckling algorithm ) is used to depress the speckle in homogeneous regions , and the macro structural information is introduced into the despeckling algorithm in heterogeneous regions to protect the structures
在统一的框架下，针对不同的描述模型的特点设计了相应的相干斑抑制方法。针对平稳区域设计了改进的acmap算法(基于模拟退火和相关邻域的最大后验估计相干斑抑制算法) ，针对非平稳区域将分割得到的宏观结构信息引入到算法中，有效的保护了宏观结构性信息。
