Description or discrimination of boundary curves (shapes) is an important problem in picture processing and pattern recognition Fourier descriptors (FD's) have interesting properties in this respect. First, a critical review is given of two kinds of FD's. Some properties of the FD's are given and a distance measure is proposed, in terms of FD's, that measures the difference between two boundarv curves. It is shown how FD's can be used for obtaining skeletons fobjects. Finally, experimental results are given in character recognition and machine parts recognition.
边界曲线（形状）的描述或区分是图像处理和模式识别中的一个重要问题。傅里叶描述符（FD）在这方面具有有趣的性质。首先，对两种 FD 进行了批判性的回顾。给出了 FD 的一些性质，并提出了一种基于 FD 的距离度量，用于测量两个边界曲线之间的差异。展示了如何使用 FD 获得物体的骨架。最后，在字符识别和机器零件识别中给出了实验结果。
