【摘要】 本文提出一种形状分析的方法,它基于R变换,适用于对目标的二维图象进行形状分析。对一些典型的二维图象的轮廓,分别用博利叶描绘子和本文所述的R描绘子进行分析,结果表明它们都具有较好的识别性能。然而,R描绘子在计算速度、对存贮容量的要求方面,具有明显的优越性。应用R描绘子进行了飞机分类以及飞机的三维运动分析和跟踪,实验结果均表明这种方法具有良好的性能。更多还原

【Abstract】 A method of shape analysis based on R transformation is presented in this paper The method is suited to the shape analysis of two dimensional image of an object. By analyzing some typical contours of two dimensional images with Fourier descriptor and the R descriptor described in this paper respectively, the results obtained show that both the descriptors are of good recognizable performance. However, the R descriptor is superior to the Fourier descriptor in both computationa! speed and requirement for storage The R descriptor is applied to the classification of aircraft types and 3D motion analysis and tracking of aircrafts, the experimental results indicate that the method presented is of good performance.更多还原
