A method for the description and identification of curved objects is described in this paper. The shape of a curved object is considered as a surface which is an accumulation of horizontal section boundaries. This is described by the coefficients of a Fourier series expansion of the proposed representative function. Each complicated feature of the shape of the object is decomposed into five simple features: elongatedness, horizontal strain, section shape, torsion, and displacement. Differences of objects as patterns are defined as pseudodistances of corresponding features. Some essential properties such as completeness of the pseudodistance family are explained theoretically. Finally, experimental results of identification of wooden block models and a doll are displayed.
本文描述了一种用于描述和识别弯曲物体的方法。弯曲物体的形状被视为一个表面，它是水平截面边界的累积。这是通过对所提出的代表性函数的傅里叶级数展开的系数来描述的。物体形状的每个复杂特征都分解为五个简单特征：伸长率、水平应变、截面形状、扭转和位移。对象作为模式的差异被定义为相应特征的伪距离。最后，展示了木制模型和玩偶的识别实验结果。
