【摘要】 本文提出了将一种快速变换(R 变换)用于对运动目标的二维图象进行形状分析的方法。对一些典型的二维图象轮廓,分别用归一化付利叶变换和本文所采用的归一化 R 变换进行分析,结果表明它们都具有较好的识别性能。然而,R 变换在计算速度、对存贮容量的要求方面,具有明显的优越性。本文还给出了用 R 变换对两幅不同类型的飞机图象进行形状分析的实验结果,也表明所用的识别方法具有良好的性能。更多还原

【Abstract】 This paper presents a method which can be used for the shape analysis of two-dimensional image of a moving object in terms of the fast transformation(R tra-nsformation).By analysis some typical contours of two-dimensional images with thenormalized Fourier transfmation and the R transformation which is used in this paperrespectively,the results obtained show that both the transformations are of good reco-gnizable performance.Howerer,the R transformation is superior to the Fourier tra-nsformation in both computational speed and requirement for storage.The experimentalresults of shape analysis for two types of aircraft images are also given,indicatingagain that the recognition method presented is of good performance.更多还原
