摘要

本文描述了利用等高线分析理论在光学遥感图像上进行飞机识别的实验结果。我们提出了一种方法,通过测量所有可能的训练集实例组合的类内和类间距离来计算轮廓项目数量和分类阈值的最优值,然后检测和最小化I类和II类错误。结合寻找最合适的参考实例和计算整个类的平均值的原则,讨论了等高线相似度度量的构造。结果表明,所提出的参数整定方法和相似函数使轮廓分析能够在紧凑的非均匀数据集上进行训练,并能够在噪声和不太详细的图像上识别飞机。

Optimal tuning of the contour analysis method to recognize aircraft on remote sensing imagery
In this paper, we describe the experimental results of aircraft recognition on optical remote sensing imagery using the theory of contour analysis. We propose the a method to calculate optimal values of the contour’s items quantity and the classification threshold through measuring within- and between-class distances for all possible training set instances combinations with followed by detection and minimization of the type I and II errors. We discuss the construction of contours’ similarity measures combining the principles of finding the most appropriate reference instance and calculating the average value for the whole class. It is shown that the proposed parameters' tuning method and the similarity function make contour analysis capable to train on compact non-uniform datasets and to recognize aircraft on the noisy and less detailed images.
