基于方向距离函数的随机集均值的置信区域

Confidence Regions for Means of Random Sets using Oriented Distance Functions

Hanna K. Jankowski, Larissa I. Stanberry

摘要:

图像分析经常涉及形状估计和图像重建。在这些问题中感兴趣的对象可以被认为是随机集合,并且人们感兴趣的是找到一个代表性的或预期的集合。我们考虑使用定向距离函数的集合期望的定义,并研究相关的经验集的性质。给出了经验平均值一致的条件,并介绍了一种计算期望集的置信区域的方法。该方法适用于真实和模拟数据的例子。

英文摘要:

Image analysis frequently deals with shape estimation and image reconstruction. The ob jects of interest in these problems may be thought of as random sets, and one is interested in finding a representative, or expected, set. We consider a definition of set expectation using oriented distance functions and study the properties of the associated empirical set. Conditions are given such that the empirical average is consistent, and a method to calculate a confidence region for the expected set is introduced. The proposed method is applied to both real and simulated data examples.
